Below are sample questions representative of the exercises included on this worksheet and related 9.57 Simple Machines and Mechanical Advantage skill assessments:

Problem 1Difficulty: Mastery

A real machine has high actual mechanical advantage but low efficiency. Which interpretation is most accurate?

AIt cannot multiply force because low efficiency makes mechanical advantage zero.

BIt must reduce both input force and input distance.

CIt creates energy because output force is high.

DIt multiplies force, but a large fraction of input energy is lost to friction, sound, or thermal energy.

Solution & Explanation:Mechanical advantage and efficiency measure different things. A machine can multiply force while still wasting a large share of input energy.

Problem 2Difficulty: Mastery

A table shows three ideal pulley options for lifting the same load: 2 supporting sections, 3 supporting sections, and 5 supporting sections. Which statement is correct?

AThe 5-section option needs the least input force but the greatest rope distance for the same lift.

BThe 2-section option needs the least input force and greatest rope distance.

CThe 5-section option requires less input force and less input distance.

DAll options need the same input force because the load is the same.

Solution & Explanation:More supporting rope sections increase ideal mechanical advantage, reducing input force. The same load movement requires pulling more rope.

Problem 3Difficulty: Mastery

Which redesign would increase output distance rather than output force in a lever system?

AUse more supporting rope sections on the load.

BApply effort closer to the fulcrum and place the load farther from the fulcrum.

CMove the fulcrum closer to the load while effort stays far away.

DMake the load arm shorter than the effort arm.

Solution & Explanation:When the effort arm is shorter than the load arm, the load end can move farther and faster. This sacrifices force advantage.
