    Please go through testing of dc machines before reading this topic. Swinburne’s test is the simplest indirect method of testing dc machines. In this method, the dc machine (generator or motor) is run as a motor at no-load and losses of the machine are determined. Once the losses of the machine are known, its efficiency at any desired load can be determined in advance.It may be noted that this method is applicable to those machines in which flux is practically constant at all loads e.g., shunt and compound machines.Steps to find the EfficiencyLet us see how the efficiency of a dc shunt…

  • For Want of a Spectrum Allocation: The Philadelphia Train Derailment

    25 May 2015 | 4:04 am
    There's a proverb of uncertain origin that begins, "For want of a nail, the shoe was lost, for want of a shoe the horse was lost; and for want of a horse the rider was lost; being overtaken and slain by the enemy, all for want of care about a horse-shoe nail."  That particular version is attributed to Benjamin Franklin, but all the various versions make the same point:  lack of attention to apparently minor details can sometimes have major consequences.  As more information emerges about the tragic AMTRAK train derailment in Philadelphia on May 12, it looks like what began as a…

  • Ownership, Access, and Freedom: The Role of Technology

    Let me present a contrast between an ownership lifestyle and an access lifestyle. Exhibit A for the ownership lifestyle is my late father-in-law Ben.  Following his marriage in 1946, he built not one, but three different small houses with his own hands, selling each one and building another while holding down surveying and drafting jobs.  Once he found steady employment with the Texas Highway Department, he bought a new contractor-built house in a growing subdivision and a new 1955 Oldsmobile, which he still owned when he died earlier this year.  From that point on, he lived…

  • Five steps to a great PCB layout for a step-down converter

    6 May 2015 | 12:00 am
    Especially for switch-mode power supplies (SMPSs), the printed circuit board (PCB) layout is a critical but often under appreciated step in achieving proper performance and reliability. Errors in the PCB layout cause a variety of misbehaviors including poor output voltage regulation, switching jitter, and even device failure. Issues like these should be avoided at all costs, since fixing them usually requires a PCB design modification. However, these pitfalls are easily circumvented if time and thought are spent during the PCB layout process before the first PCBs are ever ordered. This…

  • And a Column Shalt be Under Thine Beam

    Matt Svoboda
    27 May 2015 | 9:57 pm
    One of the most frequently made mistakes in traditional design is the misalignment of a column with regards to the beam or entablature it is supporting.  The face of the beam (on both the inside and the outside) should align with the slenderest part of the column shaft. The two things that make this a solid rule are simple structural considerations and volume of historical evidence.  When ancient stone was spanning from column to column it made sense that the beam would be centered on the column and that all load was being focused on that central portion of the capital which was directly…

    One of the most important program elements for every project is the project budget. While many people will make design decisions based on the bottom line cost, an increasingly popular trend these days is to calculate what the cost of that decision equates to on a monthly basis as it is rolled into the permanent financing of the overall project. This is easy to do with a simple Mortgage Calculator and helps to make life-cycle cost determinations for items that have a return on your investment. For example, the cost of a 3 kilowatt photovoltaic solar panel system might be about $20,000 to…

    It’s a big world out there and it’s full of opportunities. With a solid education in engineering under your belt, there are countless organizations around the world who would love to have you join their ranks. But how do you choose between them all? How do you know where to apply for jobs? What should you look for? I’ve worked for engineering organizations large and small. From a tiny design company with eight employees to a huge international business employing tens of thousands, and one or two in between. If I was starting again and looking for my first job,…
  • How and When to Ask for Professional Recommendations

    Craig the Rocket Scientist
    20 May 2015 | 9:05 am
    A funny thing happened to me the other day while I was online. OK, a lot of strange things happen to me online, but this time I was on a completely normal website. While participating in a online forum for some board game I met young engineer. He was fresh out of college and was stuck in a job he felt didn’t suit his skill set. I sympathized with him and we struck up a friendship. Then, after a few weeks of discussing various dice related topics, he broached the question: Would I help recommend him for a job he was about to interview for. He hoped that given my current position and title…

  • Getting to the root of a problem

    Chris Walker
    15 May 2015 | 6:49 am
    Last week I wrote about the importance of staying in the “problem space” for as long as you need to before making the move to find a solution. Ignoring the tendency (that most engineers seem to have) of going straight to the first viable solution though, can be tough. Wrestling with a problem for a little longer than usual is important because it increases the chance that we’ve understood it correctly. In turn, that’s important because we’re more likely to find the best (or at least a good enough) solution. But what does it actually mean to wrestle with a…
  • Advice to Grads: Getting Your Engineering Resume in Order

    Craig the Rocket Scientist
    13 May 2015 | 7:28 am
    Well it’s that time of year again! No, no, not summer – Job hunting! In the past I’ve had to write AND READ a lot of resumes. Resume styles tend to come and go like fashion design. If you ask 10 different experts they will give you 10 different templates that your resume should conform to. That’s ludicrous. When it comes right down to it, the person reading your resume doesn’t care what color or weight the paper is. They don’t care about the font or color ink you used. They care if they can quickly, and easily, scan the information in front of them and understand who you are. The…

    The goals were lofty for a wastewater treatment plant at an oil refinery in the Rocky Mountain region. The plant must treat 1 million gallons of industrial wastewater daily. The design must minimize the plant’s footprint and environmental impact, while reaching for efficiencies in capital outlay and operational costs. It’s a combination of challenges engineers face in the real world every day. Only this isn’t the real world and those charged with the design aren’t engineers — yet.

    The world’s urban population is growing. According to the World Health Organization, 54 percent of people lived in urban areas in 2014, up from 34 percent in 1960. As people flock to cities, they find fewer open spaces to enjoy. This has health experts worried. Studies show people’s brain waves differ when they spend time outdoors rather than within the built environment; people who live near open spaces are typically more physically active. Often, providing green space is a secondary consideration for city planners focused on such issues as urban sprawl, traffic congestion, pollution,…

Chou followed his adviser’s suggestion and went on to become a pioneer in advanced composites, working over the years with a wide variety of materials and processes. Almost five decades later, he is still on the hunt for innovations that will make advanced composites more affordable, reliable and functional. His latest breakthrough builds on work he did in the…
  • New Ballistic Wallpaper Bomb Proofs Combat Shelters

    John Shury
    27 May 2015 | 12:34 am
    The US Army has unveiled a new defensive product dubbed “ballistic wallpaper” designed to protect American Soldiers when they take cover in urban war zones. In urban warfare, troops will often use abandoned buildings or structures for defensive purposes instead of building their own or digging foxholes. The problem is that when these buildings come under fire by an RPG or tank round, a wall that is hit will implode sending shards of rock and mortar flying at the occupants sheltering inside. To solve this, engineers at the U.S. Army’s Research and Development Centre have come up with the…

    Mixing Blades Mixing blades (or impellers as they are most commonly referred to), make or break industrial mixing. They are pivotal to liquid mixing because they allow the right flow to be executed. In this blog, we have classified mixing blades into 3 major categories: low shear, medium shear, and high shear. It is important to understand these three categories because each impeller accomplishes a particular type of flow. Understanding the why of their shape and design can be crucial to choosing the right mixing blade for the application. Mixing blades can differ greatly due to differing…

    16 May 2015 | 2:49 pm
    While recently demonstrating a prototype to a family member I was asked, “Are you going to patent that?” While happy to see such enthusiasm, I tactfully declared that I couldn’t seek a patent, as it was built using open source components. This perplexed my family member who, being from a generation or two (or three) before me, thought that is how “inventing things” works – their words. I did my best to explain the seemingly “hippie-ish” concepts of open source, copyleft, and creative commons licenses to someone from America’s Greatest…

    14 Mar 2015 | 9:32 am
    Predicting the future of technology is a perpetual exercise in futility. But it’s fun. The evolution of personal computing is something that futurists and tech pundits like to try to predict every few years (or months). Like forecasting the weather, you are never completely right or wrong. If you were to ask me where computers, smartphones, and wearables are heading over the next 20 years I’d sit down and take inventory of the gadgets I own today. I’d also take a trip down memory lane to remember the devices I used to own. My iPhone 6 has replaced my camcorder, digital…

    While attending CES 2015, I had a minor epiphany regarding the intersection of design and technology; something new I’d not considered and which I thought might be of interest to others. However, in the course of attempting to distill my thoughts into something digestible, it occurred to me that misunderstandings might (probably would) arise from the various definitions and interpretations which accompany so many common design terms these days. How does one communicate an idea when the terms used to explain it have lost their meaning? In hopes of improving communication in general, I…

    The term Ergonomics was first used over 150 years ago, it is composed of two Greek words, Ergon meaning “work”, and Nomos meaning “law or custom”, essentially it is the “Custom of Work”. The very root of this term refers to how work is done. In the early 1900’s, the dawn of the industrial age, ergonomic concepts were developing, aiming to  improve worker productivity by achieving efficiencies through improved job processes. World War II created a strong interest in human and machine interaction, due to sophisticated and critical equipment (tanks and airplanes) being at risk…

  • Three Ways That Brakes Can Make Or “Break” Your Industrial Caster

    Ferris Ayar
    15 Apr 2015 | 7:59 am
    When choosing heavy-duty casters, you often consider the attributes that keep it rolling. But, in many applications, you’ll also want to think about whether the ability to stop that motion – using brakes – is equally important. In the industrial caster world, brakes can serve a very important role. Like brakes on a car, they allow for the ceasing of motion and locking in place. However, heavy-duty caster brakes can also add a modicum of control to the direction in which the casters are moving – a trait that can promote both efficient function, as well as safety in the workplace – by…
