Problem (1) Gears A and B each have a mass of 4 kg and a radius
of gyration of 75 mm about their centers, while gear C has a mass
of 15 kg and a radius of gyration of 180 mm about its center. A
couple moment M = (0.20) N-m is applied to gear C. Determine
the number of revolutions gears A and B experience if gear C

A stationary horizontal plate is attached to the ceiling by means ofa fixed vertical tube. A wheel of radius aa and mass mm is mounted on a light axle ACAC that is attached by means of a clevis at AA to a rod ABAB fitted inside the vertical tube. The rod ABAB is made to rotate with a constant angular velocity ΩΩ causing the wheel to roll on the lower face of the stationary plate. Determine the minimum angular velocity ΩΩ for which contact is maintained between the wheel and the plate. Consider the particular cases ( aa ) when the mass of the wheel is concentrated in the rim, (b) when the wheel is equivalent to a thin disk of radius aa
also extend the problem using Kinematic and Kinetic analysis
The 2-lb gear A is constrained to roll on the fixed gear B but is free to rotate about axle AD. Axle AD has a length of 20 in., a negligible weight, and is connected by a clevis to the vertical shaft DE that rotates as shown with a constant angular velocity w1. Assuming that gear A can be approximated by a thin disk with a radius of 4 in., determine the largest allowable value of w1 if gear A is not to lose contact with gear B.

- In the helicopter shown; a vertical tail propeller is used to pre- vent rotation of the cab as the speed of the main blades is changed. Assuming that the tail propeller is not operating determine the final angular velocity of the cab after the speed of the main blades has been changed from I80 to 240 rpm. (The speed of the main blades is measured relative to the cab, and the cab has a centroidal moment of inertia of 650 lb.ft.s2. Each of the four main blades is assumed to be a slender rod 14 ft weighing 55 lb.)arrow_forwardThe essential structure of a certain type of aircraft turn indicator is shown. Each spring has a constant of 500 N/m, and the 200-g uniform disk of 40-mm radius spins at the rate of 10 000 rpm. The springs are stretched and exert equal vertical forces on yoke AB when the airplane is traveling in a straight path. Determine the angle through which the yoke will rotate when the pilot executes a horizontal turn of 750-m radius to the right at a speed of 800 km/h. Indicate whether point A will move up or down.arrow_forwardDisk A, of weight 10 lb and radius r = 6 in., is at rest when it is placed in contact with belt BC, which moves to the right with a constant speed v = 40 ft/s. Knowing that μk = 0.20 between the disk and the belt, determine the number of revolutions executed by the disk before it attains a constant angular velocity.arrow_forward
