Determine the moment of inertia of a uniform cube when the rotation axis is along an edge. Suppose its total mass is M=2.5kg, the edges are each 10.0 cm long, it begins at rest, and a constant force, F=4.0N is applied to the edge diagonally opposite the rotation axis. The moment arm and the force are at an angle of 60 degrees. What would its angular displacement from the start be when its angular velocity is 13 rad/s? Draw the...

The diagram above shows a side view of a person’s arm. The
forearm and hand together weigh 19N (WFH = 19N). The
center of gravity at point T is located 24cm from
the elbow joint. The person is holding a bowling ball 38cm from the
elbow and the ball weighs 47N (WB = 47N).
(a) Calculate the torque produced by the weight of the forearm
and hand about the elbow joint. Include the direction of the
torque.
(b) Calculate the...

Dan's biceps muscle has a moment arm about the elbow joint of 0.011 m when the joint is held at a joint angle of 90 degrees and can produce a force of 526 N. His forearm is 0.24 m from the elbow joint center to the center of his hand where he grips a handle. His forearm has a mass of 1.2 kg and the center of mass is located directly above the elbow joint. How much force can he...
