Type of Loads

Load torque can be of two types

• Active load torque:- Active torques continues to act in the same direction irrespective of the direction of the drive. e.g. gravitational force or deformation in elastic bodies.
  
  
• Passive load torque:- the sense of the load torque changes with the change in the direction of motion of drive. e. g. torques due to friction, due to shear and deformation of inelastic bodies
