Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

A 550.0 g bird is flying horizontally at 2.50 m/s, not
paying much attention, when it suddenly flies into a
stationary vertical bar, hitting it 25.0 cm below the top
(Figure 1). The bar is uniform, 0.800 m long, has a mass
of 2.40 kg, and is hinged at its base. The collision stuns
the bird so that it just drops to the ground afterward (but
soon recovers to fly happily away).

A 500.0 g bird is flying horizontally at 2.25 m/s, not paying much at- tention, when it suddenly flies into a stationary vertical bar, hitting it two-thirds of the way up from the bottom. The bar is uniform and very thin, is 0.750 m long, has a mass of 1.50 kg, and is hinged at its base. The collision stuns the bird so that it just drops to the ground afterwards (but soon recovers and flies away). a) Using conservation of total angular momentum, determine the angular velocity of the bar just after it is hit by the bird. b) What numerical fraction of the bird's initial kinetic energy is converted to other forms of energy during the collision?
