Mathcad Prime 2.0 How To: Labels
PTC Mathcad Prime 2.0 supports a feature called “Labels”. In this blog, I’d like to describe the motivation behind, benefits and nuances of this feature. For the “old-timers” I will reflect how it relates to a similar Mathcad 15.0 feature. Background: Labels come from the well established convention in mathematics and engineering that uses different font styles for variables to …

Develop Safer, More Efficient Engineering Solutions by Sharing Resources
In our past two posts, PTC Mathcad Takes on the Demanding World of the Oil and Gas Industry and From University to the Oil and Gas Industry, PTC Mathcad A Reliable Tool you were introduced to Luke Devall, a graduate engineer who specializes in design at Neptune Subsea Engineering. In Devall’s spare time he has been working to start Enghance, a community …
Frisbee Physics: Java vs. PTC Mathcad
In a paper, V.R. Morrison discusses an interesting model of a frisbee. The author derives the equations governing the position (x, y), velocity (x’, y’) and acceleration (x’’, y’’) of a frisbee as: CD(α) is a drag coefficient at angle of attack (AoA) α, and CL(α) is the lift coefficient at AoA α, area and mass are, you guessed, the …
The Trickiness of Temperature Units
There seems to be quite a bit of confusion around using temperature units in Mathcad. When we describe the implementation and the proper way to use temperature units, the question of “Why on earth would you do it like that?” often arises. Allow us to explain… Simple units conversion In most cases, unit conversions are simple: Converting a quantity, say …

Excel vs. Mathcad for Engineering Calculations
Hey folks, as promised, here is my second installment on the topic of Excel vs. Mathcad for engineering calculations. In my first post I talked about conceptual differences between the two products and kept the details light. In this installment I will put a finer point on the differentiations. WHITEBOARD VS FORMULA BAR Mathcad is a document that emulates an …

Temperature Units
Simple units conversion Unit conversion are simple (in most cases): Converting a quantity, say length, from one unit (e.g. inches) to another (e.g. meters) involves multiplying the quantity by a factor (namely 0.0254). This is very convenient because the following calculations can be done without any ambiguity: Why am I even writing about this? This stuff is trivial. A paradox …

Smoots and Smonths (Part 2)
Last week I came across an amusing Tweet from a colleague referencing a discussion on Reddit Math: I couldn’t resist checking this out in Mathcad Prime. True enough! The quantity 10! seconds is exactly 42 days or 6 weeks in length. 60 seconds! produces a unit compatibility error in Mathcad (see below). However, it is easy enough to …
Smoots and Smonths (Part 1)
Mathcad’s unit handling capabilities and flexibility with units have always been one of the product’s most liked characteristics. I personally find Mathcad’s unit capabilities to be both a source of amusement and a catalyst for my creativity. For example, playing with a built-in Mathcad unit like the Smoot lets one think about common situations, such as free fall, in a …
Calculating the Thickness of a Steel Pole – So Easy With Mathcad!
Today, I ran into this forum discussion where a student asked for help doing a calculation. The task was to calculate how thick a steel pole would need to be to hold a hanging object with a defined weight: “… If I have a solid steel pole with a length of 50 cm, hang this from a roof, and want …

Mathcad A-Z: L is for Labels
Labels what you might ask? Labels are a new feature in Mathcad Prime 1.0 that allow you to assign different meanings to the same character. A label is a way of designating a math type such as variables, constants and units. A label allows you to format all units, say to a certain look. We developed labels because sometimes you …
