Question

the mechanical advantage of an inclined plane is greater than 1 because the output force is less than the input force. true false

Explanation:

Mechanical advantage (MA) is calculated as \(MA=\frac{\text{Output Force}}{\text{Input Force}}\). For an inclined plane, the output force (force to lift the object vertically \(F_{out} = mg\)) and the input force (force along the inclined plane \(F_{in}=\frac{mg}{\text{Length of incline}/\text{Height}}\)). Since the length of the incline is greater than the height, \(F_{in} 1\) (because output force is greater than input force, not less as stated in the question).

Answer:

FALSE
