The moments of inertia of the parts attached to the input shaft A is 0.019 kgmand that of the parts attached to output shaft B is 0.1 kgm2If input shaft A exerts a constant torque of 7.27 Nm and is geared to output shaft B, calculate the following:

 

  • The gear ratio gives the maximum angular acceleration of output shaft B.
  • The corresponding angular acceleration of each shaft.
