Mechanical Engineering Problem sets for a problem member

Click For Summary
The discussion centers on the challenges of engineering courses, particularly thermodynamics and strength of materials, in comparison to undergraduate mathematics. The original poster acknowledges a previous post was locked due to an insult but expresses a desire to engage constructively. They seek examples and problem sets to better understand the difficulty of these engineering subjects and inquire about the concerns regarding accelerated summer courses in thermodynamics. A specific mechanics of materials problem is presented, involving a simply supported bridge with defined parameters, to illustrate the type of challenges faced in these courses. The conversation highlights the complexities of engineering coursework and the need for supportive dialogue among members.

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.

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

Thread 'Uncertainty in pursuing Engineering'

This is my second year in college, and I changed my major to electrical engineering at the start of my second year. I'm taking Calc 1, and I know that I'm going to fail the course. I think there are several reasons for this. I hadn't touched math in an entire year (finished pre-calc 2 in HS), and I heard Calc 1 was the easiest math course, so I decided that taking the class without outside help (tutors or office hours) was enough. I tried really hard and spent hours learning, studying, and...
