Question

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, ar [f/s). 9 Q1 what is the magnitude of angular velocity of gear D, oo [rad/s)? Q2: What is the magnitude of angular acceleration of gear D, a [rad/s? Q3: What is the magnitude of acceleration of point P on gear D, ar [f/s 1?
