MecMovies 4.0 : M6.18: Motor-driven Shafts

Diagram shows two shafts marked 1 and 2 of length 36 inches and 96 inches respectively. They are connected by two gears at B which has 24 teeth on the shaft 1 and at C which has 72 teeth on the shaft 2. The shaft 1 is connected to a motor at A. The shaft 2 has a gear at D on which a torque T subscript D is applied.

7. Compute the angles of twist in shafts $(1)$ and $(2)$ .

8. Compute the rotation angle of gear $B$ from the angle of twist in shaft $(1)$ .

9. Use the rotation angle of gear $B$ and the gear ratio to determine the rotation angle of gear $C$ , taking care to account for the change of rotation direction between the two shafts.

10. Finally, compute the rotation angle of gear $D$ from the rotation angle of gear $C$ and the angle of twist in shaft $(2)$ .
