Centroid of a cosine shaped rod

There's a problem in Hibbeler's 14th edition of Statics for Engineering that I've tried a few times and couldn't solve. The problem is shown below. It wants me to find the centroid coordinates of a ...

Controlling the motion of points in an animation

I am looking for a better way to show this behavior on a pressure-composition diagram for immiscible liquids (two black dots show behavior at different x-positions, only one is present otherwise): ...

Euler-Bernoulli cantilever beam with parabolic load

How do I get the displacement in the free end of a bar with Parabolic load (I.e. in point with length L)? I found the information on a site, but only I found for uniform load. Someone who ...

Tracing the line of motion of a point in graphics

I'm a beginner in mathematica. I'm making a nb that calculates the output angle of a fourbar mechanism based on the input angle. So the input is the length of the four linkages and the input angle of ...

FEM Solution desired for “Plate with orifice” deflection: Application of Boundary Conditions and use of Regions

I found the deflection of an orifice plate (circular plate with a hole) subject to uniform pressure using Mathematica's NDSolve functionality. The plate is fixed at its outer circumference and is ...

Book about using Mathematica in real world engineering projects

So far I've abused Mathematica by only using it as a notebook. That's a big waste since I've bought a student-life time Mathematica 9 / SystemModeler license. My problem is that I'm not inspired to ...
