Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. is a measure of how much a machine multiplies force or distance.
2. The ratio of the output force to the input force is called the .
3. The ratio of the input distance to the output distance is known as the .
4. No machine is 100% efficient due to .
5. Which of the following is NOT a simple machine?
Lever
Bicycle
Pulley
Inclined Plane
6. A machine with an ideal mechanical advantage (IMA) of 4 means:
It multiplies force by 4.
It multiplies distance by 4.
It reduces force by 4.
It is 4% efficient.
7. A construction worker uses a lever to lift a 200 kg rock. If the output force required is 2000 N and the input force applied is 500 N, calculate the Actual Mechanical Advantage (AMA) of the lever.
8. An inclined plane is 10 meters long and 2 meters high. Calculate the Ideal Mechanical Advantage (IMA) of the inclined plane.
9. If the inclined plane in the previous question has an AMA of 3, what is its efficiency?
10. In an ideal machine, the work input is always equal to the work output.
True
False
11. A pulley system always increases the force applied.
True
False
12. Describe a real-world scenario where a wheel and axle system is used to achieve mechanical advantage. Explain how it works.
