FE Mechanics of Materials Review Session 2022

FE Exam Review Session: Mechanics of Materials
Problem sheets are posted below. Take a look at the problems and see if you can solve them ahead of time. See the video for solutions. Feel free to ask questions!

This is a question based review with questions that will cover topics that address each topic in the NCEES FE Civil exam specification.
These topics include:
Mechanics of Materials
A. Shear and moment diagrams
B. Stresses and strains (e.g., diagrams, axial, torsion, bending, shear, thermal)
C. Deformations (e.g., axial, torsion, bending, thermal)
D. Combined stresses, principal stresses, and Mohr's circle

Hey Mark! I watched these a year ago when I took my FE and you did such a great job that I’m coming back for a refresher before I take my PE in 14 days. You are an amazing instructor. Fun to watch, easy to understand, and inspiring. Thank you sincerely.

this man more goated than Lebron James

Yo Mark, do more videos. Your our only hope. Everyone is charging 100 per hour

[mrdjf]

These videos are fantastic!! I wish I had taken the FE while I was still in school, but some of my peers have recommended these videos and they’re really helping me refresh on all the material!

What a wonderful method of teaching, i just passed my FE. Your videos helped me a lot, thank you.

[aliwow]

Thank you so much Mark. I passed the FE exam today on my first attempt. Your videos help a lot. I watched all your review session and bought an exam sample on NCEES site.

My first statics class where I learned shear and moment diagrams was in 2016. I'm out of college and grad school and just started my first job and I'm trying to pass the FE. This single video has helped me learn shear and moment diagrams when taking this class 3 times in undergrad did not. Thank you!

Hello Mark, on question 12 you should calculate M as P*e, where e would be the eccentricity from the neutral axis of the square section and P the axial load. In this case, e would be equal to 45 cm. Then you can determine the stress in point A as the algebraic sum of bending and axial stresses. For instance, imagine if I wanted to calculate the stress on the opposite side of the section, as you mentioned in point B. Here, the moment would be the same, and bending stress would be adding to the axial stress; both in compression. Please correct me if I am wrong. By the way, your videos are very helpful; thank you!

I just took and passed my Fe on 6/5/24 and question 6 from this review was a problem on the exam I took

[fabulosospucas]

I really appreciate your videos, I have my fe exam in 10 days and this has really helped.

[purplerambutan]

I just passed the FE exam 2nd take! Would really recommend Mark's videos for concept training! I passed after 15 YEARS since I graduated from college! Glory to God my Lord Jesus!

Thank you so much sir, you made a great work that you shared your knowledge to us, very optimistic and very kindly man. And actually, I am watching your videos for refresh my memory in my major, and this the best review I have been seen. You don't know how I appreciated you for this professional and honest explanations, and love to help others.

Thanks dear

On Question 12 (#12), it is asking for the maximum combined stress. Why then would the maximum stress not be = - axial stress - bending stress?

[lucasvansickle]

Question 12, Pg. 13 of15: Why did you use I=(bh^4)/12 versus I=(bh^3)/12?
I graduated in 2008 from FSU. Your videos are fantastic and they are really bringing it all back to me! Thank you!

On Question 14 (#14), the reference handbook provides the formulas for the principal stresses on page 132 if you don't want to draw a Mohr's Circle.

[thomassbahtu]

Hi Mark I appreciate the conceptual explanation of Mohr's circle. Now I know the evolution of principles stresses.

[carlossosa]

I wish my School Tied Trig Back into Everything like you do its crazy how much it helps

[donwilliams]

Problem #12. You illustrated the area to be 100 mm^2. How are you deriving that? 10cm x 10cm = 100 cm^2 = 0.01m^2.

[fouzianoutash]

Oh my God, you are great, even though, l am a second language and my English is not great, but I fully understand your explanations, especially the last three questions. You helped me a lot. You made me anxious and hopeful for the exam.
May God bless you always
Thank you so much.

For problem 3 why do we only solve the first and last one?
