Chapter 15, Problem 8 The rotor of a gas turbine is rotating at a speed of 6900 rpm when the turbine is shut down. It is observed that 4 min is required for the rotor to coast to rest. Assuming uniformly accelerated motion, determine ( a ) the angular acceleration, ( b ) the number of revolutions that the rotor executes before coming to rest.
Chapter 15, Problem 10 The assembly shown consists of the straight rod ABC , which passes through and is welded to the rectangular plate DEFH . The assembly rotates about the axis AC with a constant angular velocity of 9 rad/s. Knowing that the motion when viewed from C is counterclockwise, determine the velocity and acceleration of corner F .
