A stick of uniform density with mass M = 7.8 kg and length L = 0.8 m is pivoted about an axle which is perpendicular to its length and located 0.11 m from one end. Ignore any friction between the stick and the axle.
a) What is the moment of inertia of the stick about this axle?
Iaxle = ?? kg m2
The stick is held horizontal and then released.
b) What is its angular speed as it passes through the vertical
w = ?? rad/s
c) What is its angular acceleration as it passes through the vertical position?
a = ?? rad/s2
d) What is the magnitude of the vertical component of the force exerted by the stick on the axle when the stick passes through the vertical?
|Fvertical| = ?? N
