The electric motor with an attached disk is running at a constant low speed of 105 rev/min in the direction shown. If the motor pivots about the x-axis at the constant rate y = 9.8 rad/sec with no rotation about the Z-axis (N = 0), determine the angular acceleration a of the rotor and disk as the position y = 30° is passed.

Transcribed Image Text:The electric motor with an attached disk is running at a constant low speed of 105 rev/min in the direction shown. If the motor pivots
about the x-axis at the constant rate y = 9.8 rad/sec with no rotation about the Z-axis (N = 0), determine the angular acceleration a of
the rotor and disk as the position y = 30° is passed. Also find the velocity and acceleration of point A, which is on the top of the disk at
this instant.
OC = 16"
CA = 7"
