Question

The rectangular object in the figure below consists of four masses connected by light rods. What power must be applied to this object to accelerate it from rest to an angular speed of 2.63 rad/s in 5.2 s for the following cases. Give answer in 4 significant figures

(a) the object is rotated about the x-axis ( )W
(b) the object is rotated about the y-axis ( )W
(c) the object is rotated about the z-axis (which is through the origin and perpendicular to the page) ( )W

Explanation / Answer

The initial angular speed i = 0

The final angular speed f = 2.63rad/s

the time interval t = 5.2s
