[SOLVED] How far does the bucket fall?
Homework Statement
A cylindrical pulley with a mass of M = 5.7 kg and a radius of r = 0.66 m is used to lower a
bucket with a mass of m = 2 kg into a well. The bucket starts from rest and falls for 3.5 s.
The acceleration of gravity is 9:8 m/s^2 ...
Homework Statement
A uniform disk of radius 0.12 m is mounted on a frictionless, horizontal axis. A light cord wrapped around the disk supports a 1 kg object, as shown in the figure from rest the object falls with a downward acceleration of 2.3 m/s^2.The acceleration of gravity is 9.8 m/s^2...
Ohhhhh, ok so its 8.628+-gravity/5.184 ? t/I? Would the force down due to gravity be mg(l/2)= force of gravity? if so do I subtract that from the 8.628 force up? so the force of gravity is 31.704 and the torque up is 8.628? Then would I have to convert that answer to radians?
So Net torque would = 2.4 *4(sin64)=8.628? or the net force is 9.81 down - 8.832 up? = -.968 Net force?
How do I account for gravity?
So the moment of Inertia would be (ML^2)/3 which is I=(2.7*(2.4)^2)/3 = 5.184, but how does it work into Newtons second law, and how does it help me...
[SOLVED] Magnitude of the angular acceleration about the pivot point?
Homework Statement
A uniform horizontal rod of mass 2.7 kg and length 2.4 m is free to pivot about one end as shown. The moment of inertia of the rod about an axis perpendicular to the rod and through the center of mass...
