Gear A starts from rest and accelerates uniformly with ??-0.8 [rad/s, in direction shown. Gears B and C are fastened together and rotate together. Radii of gears are: r in],r 8 [in], rc 4 [in], and ro-6 [in]. After A has rotated through ?0A-3 [rev], determine: (a) the magnitude of angular velocity of gear D, oo [rad/s], (b) the magnitude of angular acceleration of gear D, an, [rad/s'], and (c) the magnitude of acceleration of point P on gear D,...

A mechanical device consists of two circular gears, one of radius 2 centered at (0, -2) and the other radius 1 centered at (0, 1). The gear of radius 2 rotates clockwise at unit angular velocity (1 radian per second), while the gear of radius 1 rotates counterclockwise without slipping at the contact point. The two gears each carry a small peg on their circumference, and these pegs are connected together by an elastic band. Initially, both pegs are at...

Part E should say gear C not gear B
A gear reduction system consists of three gears A, B, and C. Gear A start from rest at time t = 0 and rotates clockwise with constant angular acceleration. Knowing that the angular velocity of gear A is 600 rpm at time t = 2s, determine (a) the anglular accelerations of gears B and C, (b) the accelerations of the points on gear B and C which are in contact when...
