The class I am taking is algebra based, but I don't know what approach to use to start the problem. I am not sure what to do. Someone told me to do R= g/w^2 and A= woR/w...so sin theta= A/R and you would get your angle, but that is wrong. Any other thoughts?
Homework Statement
Suppose at t=0, theta=0 degrees a pendulum swings to the left with angular velocity wo=47.5 rad/s. Find the magnitude of the maximum angle theta for the oscillation. Given w=60.7 rad/s, and wo=47.5 rad/s, where w is angular frequency of the small oscillation. Answer in...
Thanks! if i get q16 ill let u know...i can't seem to figure it out either...i hate to bug u but how did u figure out question 18 about the velocity of the wheel?? i got 17 but i don't know how to do number 18. please let me know...i haven't answered very many questions on this hw
but for this question u aren't given a radius. i need q15 on homework 23 (part b)...for part a i did torque= I x angular acceleration and i got it right like you said...
for part b...how do i do it? i get what you are saying...but it says the wheel comes to REST after 73 seconds.. so if u do...
yeah...this homework has really been giving me problems. i just want to finish. any help would be nice. its always good to have extra help from other people in the class
The combination of an applied force and a frictional force produces a constant torque of 34 N.m on a wheel rotating about a fixed axis. The applied force acts for 9.1s, during which time the angular speed of the wheel increases from 0 to 16 rad/s.
a)What is the moment of inertia of the...
How about this?? It's the second part to the question...
Assume that k=1/2
QUESTION...If this system is released from rest, find the speed, v, at the moment when the weight has descended a vertical distance h. Any help would be nice.
Thanks
