this link didn't helped at all sir... pls give the diff eqn at least

so, in this kind of forced SHM , what will be the eqn of motion?? pls try to do this question once.. I have been trying it from many days

pls help me and tell whether it is correct or not

I think I can put the concept of whirling shaft in it... so I put the formula for amplitude as , y=e / (_{}Wn / _{}W )^2 -1

Homework Statement Question:There is a fixed end beam PQ. It is carrying a motor M. The motor is unbalanced and when the motor is rotating ,it is making the beam to vibrate with a frequency equal to the speed of the motor. A small mass is kept at point A just above the motor on the beam. it...

heyy...some one help me out with this question

yeah, angular speed...pls solve it quickly, grave need

@cupid: u can assume the speed of motor as N. This is equal to the frequency of vibration of beam (base).

wat u did is conventional. but pseudo force takes place when the system is in non- inertial frame of ref. Refer google with the term "pseudo force", u'll definitely get what I am trying to say

is my answer correct??

dude, the answer is ay= |g-A| /2 it can be brought by simply using the pseudo force on the block. :approve:
