Gear A is between a stationary gear rack F and the gear rack E, which is moving at vE=6 ft/s to the right at the instant shown. It is also observed that the acceleration of gear A is 2 ft/s2 also to the right. At this same instant, determine the angular velocity and angular acceleration of disk B. Use RMA for velocity analysis.
Imagine that the CD on the right side is rotating with a constantangular velocity of �=6 rad/s between t=0 and t=3 s. Then, at t=3 s,it is suddenly subjected to a constant angular acceleration of α=6rad/s2 for 2 seconds. Determine the number of turns for the totaltime interval from t=0 to t=5 s. (Diameter of the CD is 12 cm)
At the instant shown in the figure below, the arm AB of the conveyor belt is rotating about the Y axis with a constant angular velocity ω1 = 12 rad/s, while the arm is rotating upward at a constant rate ω2 = 8 rad/s. At that instant, the package is a distance r = 12 m from A, and the conveyor belt is running at a constant speed of ̇r = 10 m/s. Determine the velocity and acceleration of the package P at the instant shown. Neglect the size of the package.
