hi folks, my back story is that I have failed my strength of materials and dynamics twice. the college I am attending put these courses in an accelerated time frame... this means 14 weeks of material turned into 7 weeks of material. I am not able to learn at that pace, hence why I failed twice.
I am not in these courses right now, but am trying to grasp the concepts so it doesn't happen again.
currently I am trying determine the force acting into a reciever when a slender rod with a mass of .033KG rotates 15degrees in 60 seconds and comes to a complete stop. the radius of rotation is .2542m
my calculations:
Omega=(theta)/t
=15/60
=.25 <<--------is this correct?
with this I can determine my angular acceleration:
(alpha)=dw/dt
=.25/60
=.0042 rad/s²
not sure what calculation to goto next. I have tried the parallel axis, I have tried the KE equation... not sure which path to take. this is where it gets REALLY FOGGY!
this is about as much as I picked up in class as the rest of this process is a complete blur... any help would be GREATLY appreciated.
