Assume that the gear keyed to the shaft shown in the figure below is a Class 50, cast iron flywheel of 15-inin outside diameter and 1-in thickness. The hub is 4-in dia and 3-in thick. The shaft is steel.   Determine the critical frequency of shaft whirl for the assembly shown using the following dimensions: a = 4 in , b = 12 in , l = 14 in , the shaft diameter is 2 in. Assume the following: The applied transverse force PP  and the Torque TT to be zero. The mass of the steel shaft can be ignored.

Assume that the gear keyed to the shaft shown in the figure below is a Class 50, cast iron flywheel of 15-inin outside diameter and 1-in thickness. The hub is 4-in dia and 3-in thick. The shaft is steel.

 

Determine the critical frequency of shaft whirl for the assembly shown using the following dimensions: a = 4 in , b = 12 in , l = 14 in , the shaft diameter is 2 in. Assume the following:

  1. The applied transverse force PP  and the Torque TT to be zero.
  2. The mass of the steel shaft can be ignored.
