Diagram shows a shaft A B C containing two gears at B and C which is connected to a motor A where the torques of 20 Newton meter and T subscript c is applied on B and C and the distance A B is 1400 millimeter and B C is 1000 millimeter. The x axis is taken along the axis of the gears and the y axis is taken along the motor support at A and perpendicular to the x axis.
