1.For the following simple see-saw calculate: 1. the load that could be lifed, 2. the maechanical advantage (assume the lever is 100% efficient).

A simple wheel and axle is used to life a bucket out of a well. The radii of the wheel and axle are 20 cm and 4 cm, respectively. Determine: 1. The velocity ratio (and so the IMA), 2. The thoretical effort required to life a load of 30 N assuming no energ...
