In a pulley system with four supporting ropes, how much force is needed to lift a 200 lb load (ignoring friction)?
Answer: 50 lbs
With four supporting ropes, the required force is the load divided by four: 200 ÷ 4 = 50 lbs.
What is the primary purpose of a flywheel in a mechanical system?
Answer: To store rotational energy and smooth out power delivery
A flywheel stores kinetic energy during power strokes and releases it during dead spots to maintain consistent rotation.
If a ramp is 12 feet long and 3 feet high, what is its mechanical advantage?
Answer: 4
The mechanical advantage of an inclined plane equals length divided by height: 12 ÷ 3 = 4.
Two meshed gears rotate in which relative direction?
Answer: Opposite directions
When two gears are meshed directly, their teeth interlock causing them to rotate in opposite directions.
Which material property describes its ability to return to its original shape after being deformed?
Answer: Elasticity
Elasticity is the ability of a material to deform under stress and return to its original shape when the stress is removed.
A lever arm is 6 feet long with the fulcrum placed 2 feet from the load. What is the mechanical advantage?
Answer: 2
The mechanical advantage is the effort arm (4 ft) divided by the load arm (2 ft): 4 ÷ 2 = 2.
