An automotive engineer realizes it will be difficult for drivers to turn a pick up truck with a steering wheel that has a radius of only 11.0 cm . What can the engineer do to increase the mechanical advantage of the steering wheel?

A 3.0-kg ball and a 1.0-kg ball are placed at opposite ends of a massless beam so that the system is in equilibrium as shown. Note: The drawing is not drawn to scale. What is the ratio of the lengths, b/a?

Consider the 18-speed bicycle with 21cm cranks and 45cm wheels. If the sprockets at the crank and the rear drive wheel are the same size, then calculate the ratio of the output force on the tire to the input force on the on the pedal.

Consider a hydraulic press. When the input piston is depressed 20cm, the output piston is observed to be move 1cm. On the same press, an input of 1N can raise no more than ________________.
