Statics Problem (Answer currently on Chegg is wrong)

Calculate FM, but the system moves from 5 degrees to 70 degrees. I will use the formula later on to create an automatic calculator to determine FM for 5 degrees to another angle. FM changes as a result of change in angle because there is a lever and so the moment changes.

This question is unique since it is heavily modifided question found on the internet (textbook)... So the answer obtained on the internet will be wrong

Explanation / Answer

Fm*0.05*sintheta = 2*9.8*0.15*costheta + 5*9.8*0.35*costheta

Fm = 401.8/tantheta = N <_---answer

for 5 degrees

Fm = 4592.6 N

for 70

Fm = 146.24 N
