MecMovies 4.0 : M6.7: Multiple Torques

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 600 Newton meter and 200 Newton meter is applied on B and C and the distance A B is 100 millimeter and B C is 300 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.

A solid circular drive shaft connects a motor to gears $B$ and $C$ . The torque on gear $B$ is $600 N - m$ and the torque on gear $C$ is $200 N - m$ , acting in the directions shown. The drive shaft is steel $(G = 66 GPa)$ with a diameter of $d = 25 mm$ .

• Determine the maximum shear stress in shafts $(1)$ and $(2)$ .

• Determine the rotation angle of $C$ with respect to $A$ .
