Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following is NOT considered a simple machine?
Lever
Bicycle
Pulley
Inclined plane
2. Mechanical advantage is defined as the ratio of:
Input force to output force
Output force to input force
Work input to work output
Distance moved by effort to distance moved by load
3. A simple machine that consists of a bar that pivots around a fixed point is called a .
4. The mechanical advantage of an inclined plane is calculated by dividing the by the height.
5. Explain how a pulley system can be used to reduce the force required to lift a heavy object.
6. Consider the inclined plane shown below. If the length of the ramp is 5 meters and the height it elevates an object is 1 meter, what is the ideal mechanical advantage of this inclined plane?
Show your work:
7. A wheel and axle is a variation of a lever.

False
8. The actual mechanical advantage of a machine is always greater than its ideal mechanical advantage due to friction.
True
False
