Welcome to TBP Theta Chapter's FE Review Headquarters! This is where we post video tutorials on specific questions regarding the FE exam, as well as answer any questions or concerns you may have about it! Some of us here have passed the exam ourselves and would love to share our experience as well as some pointers on passing.
We are a growing team so we would highly appreciate feedback on all that we do, it can really help a lot!
On the second problem, the fundamental identity that 1 Ampere = 1 coulomb / 1 second helped it make sense for me. Along with the 1.6E-19C charge of an electron, it's pretty simple. Unfortunately, that 1A=1C/1s is not clearly in the FE handbook.
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 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.
The answer to the 3rd questions is wrong. It is supposed to be B. You just copy pasted the solution from the book and the book solution is wrong. Book solution missed up p and n value and multiplied p value with Un and n value with Up.
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.
Though your efforts to help prepare students for the FE exam are acknowledged, it’s demeaning, and rather infuriating to find that somebody in an engineering discipline, could not find a better way to deliver the material than using a smartphone that causes people to barely be able to see what’s on the screen. Additionally, you had to keep switching between applications and had to be holding a phone camera with an unsteady hand, not caring to find a phone stand or something of the sort to stabilize the camera. I am sorry if I sound rude, however, as happy as I was learning about your class, after watching the first five minutes I frankly felt insulted, with having to waste my time watching material that I deemed important, but that unfortunately wasn’t delivered with enough care or consideration to the viewer. I know you can do better than that. Please excuse the tone of my message.
