Q3. Catching a falling block of wood. The uniform rectangular panel is falling vertically with speed vi when its small peg A collides with and engages a receptacle. The collision happens over infinitesimal time. The block then pivots about the point A, which has come to rest due to the impact. Determine the angular velocity of the body as well as the x and y component of the velocity of the mass-center just after the impact. Hint: The total angular momentum of the block about A is conserved across the collision. ( Note that angular momentum about G is not conserved, because there is an 'infinite' force at A due to the collision. The angular momentum about A is conserved because all forces are finite except the force at A, which does not produce a moment about A. The finite forces cannot change momentum in infinitesimal time. ] OG 76 8 6/2

A torque T of 100 N-m is applied to a wheel D having a mass of 50 kg. a diame- ter of 600 mm, and a radius of gyration of 280 mm. The wheel D is attached by a light member AB to a slider C having a mass of 30 kg. If the system is at rest at the instant shown, what is the acceleration of slider C? What is the axial force in member AB? Neglect friction everywhere, and neglect the inertia of the memberAB. (Draw FBDs)

The 10-Ib sphere and 7-ib block (shown in section) are secured to the arm of negligible mass which rotates in the vertical plane about a horizontal axis at O.

Corner point A of the uniform square plate, with a mass of 25 kg and a side length of = 0.21 m, is pinned freely to the collar, which has an acceleration of a = 4.9 (towards the right) along the fixed horizontal shaft.

bucket of mass m is hanging from the free end of a rope whose other end is wrapped around a drum (radius R, mass M) that can rotate with negligible friction about a stationary horizontal axis. The drum is not a uniform cylinder and has unknown moment of inertia. When you release the bucket from rest, you find that it has a downward acceleration of magnitude a. What are (a) the tension in the cable between the drum and the bucket and (b) the moment of inertia of the drum about its rotation axis?
The gear shown has a radius R=150mm and a radius of gyration k =125mm. The gear is rolling without sliding with a velocity V1 of magnitude 3 m/s when it strikes a step of height h=75mm. Because the edge of the step engages the gear teeth, no slipping occurs between the gear and the step. Assuming perfectly plastic impact, determine the angular velocity of the gear after it has rotated to the top of the step.
