A strap, rod, or something comparable is used to spin up the disc. T imagine someone hand-starting a lawnmower. If he pulls the strap with a final speed before pulling the strap away, what is the rotation rate of the disk, w in rev/s? The moment of inertia of a disc is 1/2MR?. There's no sliding. • Strap's final speed = v = 0.74 m/s. • The disc's radius is R = 0.7 m • The small disc's radius is 1 cm • The disc's mass is M = 0.7 kg
Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. An overhead door is guided by wheels at A and B that roll in horizontal and vertical tracks. When = 40°, the velocity of wheel B is 2.1 ft/s upward. 5 ft A B 5 ft TOMTOTO Determine the angular velocity of the door. (You must provide an answer before moving on to the next part.) The angular velocity of the door is rad/s.
