The forearm of a person has a moment of inertia of 0.08 kgm^2 about the elbow joint. the forearm is held vertically and the bicep muscles exerts a horizontal force on the forearm at a perpendicular distance of 2.1 cm from the elbow's rotation axis. if the forearm has the resulting angular acceleration of 1.2 rad/s^2, what is the magnitude of the biceps muscle's force?

In the figure below, the bar has moment of inertia 0.4 Kgm^2 and is spinning clockwise, around an axis passing through the depicted point and perpendicular to the plane of the page, with angular speed of 10 1/s (or 10 rad/s). The 4 N depicted force, generates a constant torque (which slows down the bar rotation) for 2 seconds. Calculate the magnitude of the applied torque. Calculate the angular speed of the torque at t = 2 s.
