Mechanical Engineering Problem sets for a problem member

[dsaun777]

I got my last post locked due to insulting a member here. I do apologize I'm under a lot of stress and was nothing personal. The post was about the level of difficulty of engineering courses compared to those of mathematics at the undergraduate level. I am just curious if anyone would be kind enough to respond, despite my last failed post, and maybe share some examples and problem sets for such courses. In particular problem sets in thermodynamics or strength of materials. I just want to see what it is that I'm up against and why some members believe it is not a good idea to take an accelerated summer course in thermordynamics.

Here is a mechanics of materials problem for you to consider.

A bridge is simply supported at each end and also on two piers within the length. The piers are a distance S from each end of the bridge, and also a distance S apart (the total length of the bridge is 3*S). The bridge is considered as a uniform beam with Young's modulus E and area moment of inertia I. A load W is applied downward at a distance 1.65*S from the left end of the bridge. Determine the reactions at each of the four support locations.

and area moment of inertia I

You're too kind. You might have said the bridge has width w and thickness h.
