Applied Dynamics - Assignment 11-5 Angular Motion with Uniform Acceleration When a small plane touches down on a landing strip, its wheels accelerate from rest to a speed of 1200 rpm in 2.5 seconds. Calculate the average angular acceleration. Calculate the number of revolutions of each wheel in this time period.

Applied Dynamics - Assignment 11-5 Angular Motion with Uniform Acceleration A propeller fan 3 m in diameter used in a cooling tower comes to rest with uniform deceleration from a clockwise speed of 700 rpm. If it turns through 18 revolutions while stopping, calculate the time that it requires to stop.

Applied Dynamics - Assignment 11-6 Relationship between Rectilinear and Angular Motion Wire for a transmission line is unrolled from a reel at a rate of 850 ft/min. The radius of the reel is 3 ft for the instant considered. What is the angular speed of the reel in rpm?

Applied Dynamics - Assignment 11-6 Relationship between Rectilinear and Angular Motion As shown in the figure, weight D is suspended by a rope wrapped around pulley C. Pulleys Band C are fastened together and pulley A is belt-driven by pulley B. Starting from rest, weight D drops 20 m in 2.5 seconds. Determine the number of revolutions for each pulley. Determine the angular velocity for each pulley. Determine the angular acceleration at t=3 seconds for each pulley.
