A longer, shallower inclined plane gives a mechanical advantage that is:
ALarger
BSmaller
CZero now
DNegative
Answer & Solution
Correct answer: A. Larger
1. The mechanical advantage of a ramp is its length over its height.
2. Making the ramp longer raises that ratio.
3. So a longer, shallower ramp has a larger mechanical advantage.
4. The answer is larger.
