- To study the overdrive speed.
- To demonstrate the operation of an epicyclic gears system to obtain the overdrive speed.
- To determine the angular displacement at the input and output and to compare it with the overdrive reduction ratio calculated.
- To determine the minimum effort required at the input to raise a load at the output in an overdrive reduction ratio.
- Power transmission: checking the ratio between input torque and output torque for an overdrive reduction ratio.
