Homework Statement
A rod of mass M and length l rotates in a vertical plane about its centre which is on a frictionless, horizontal pivot. On the ends of the rod are point-like masses m1 and m2, where m1 != m2.
a)moment of inerta about the center of the rod
b)Determine the angular momentum when the angular velocity is ω
c) Determine the angular acceleration when the rod makes an angle of θ with respect to the horizontal z-axis. For m1 > m2 what is the direction of the torque?
d) At what angle θ is the angular velocity ω the greatest?
The Attempt at a Solution
So I would know how to do this question without the point masses m1 and m2, what they do is change the centre of mass of the rod, so does this question have something to do with the change in the centre of mass? Also what does it mean when the rod makes an angle of θ with respect to the horizontal, does this mean it is slanted?
