Hello,
I'm trying to plot a function from Hibbeler Mechanics of Materials in Mathcad Prime 3.0 but I'm not getting any results.
I put in a figure for P (15N) and for A (100mm^2). So the bar on top of the page isn't rectangular but square (10x10mm)
Theta = 30deg is not producing any result.
Somewhat below on the right I tried to list all theta angles from 90deg to 0deg: no result.
Obviously I do something wrong here. Please help.
Thanks maurits
Hello,
the problem is the way you are writing the equation for Sigma(Theta). You are multiplying Sine with Theta which makes no sense. You have to write "sin(theta)", whereas you write "sin * theta". When you correct this, the graph will work.
Correct your area to use the right units as well (not mm, but mm^2), otherwise you will not get stress as a result (MPa).
