###### Question details

A complex gear train has 5 gears. Gear A is the driver with 8 teeth; Gear B meshes with Gear A and has 16 teeth; Gear C shares an axle with Gear B and has 24 teeth; Gear D meshes with Gear C and has 12 teeth; Gear E meshes with Gear D. Assume the driver gear is on the left and the final output gear is on the right.

- If the system gear ratio is 4:1, how many teeth does Gear E have?
- If Gear A rotates at 50 rpm, how fast is gear B rotating?
- If the torque on Gear C is 10 in-pounds, what is the torque on Gear E?
- If Gear D has a diameter of 1.25 inches, what is the diameter of Gear E?
