I just wanted to let you know that I pass the FE exam (Mechanical). Thank you so much. Your lectures helped me a lot. I got the result today. Thank you.
for problem two you could just assume that y (or h) initial is the same as y final which is zero, and then use the function for change of height, and use the system solver - still 7.7 sec.
Appreciate the upload and guidance. For problem 4, I think it would have been helpful if you went through the process of solving it using the reference handbook instead of an equation that you know off the top of your head. Providing us with something else to memorize for this specific type of problem isn’t very helpful
I have a question. In the last exercise you calculated BC: cos30 and AC:sin30, why not the opposite? Can point C be in the intern area? making it BC: sin30 and AC:cos30 ?
To determine if a trig function should be sine or cosine, look at the limiting cases. Explore what should happen if the angle equals zero, and if the angle equals 90 degrees. Explore what should happen, when A=B*trig(theta). If A should equal B when theta = 0, and A should equal zero when theta = 90 degrees, then it is cosine. If A should equal zero when theta=0, and A should equal B when theta = 90 degrees, then it is sine.

Congratulations.
Em what type of M/C design problems u have been asked.

Great little review

I wish he would have solved the banking angle by using equations from the FE reference guide
It's basically solving for the radial acceleration (equation in FE manual) and using that in F=ma to solve for it. You end up with ma = mg sin(theta)

not a good video, they do not use equations from handbook
