Good luck, and remember: Every machine, from a hammer to a car jack, relies on the math you just unlocked.
No. Efficiency cannot exceed 100% because it would violate the law of conservation of energy. The student likely mis-measured input or output force/distance. Good luck, and remember: Every machine, from a
Mechanical advantage (MA) is a measure of the force amplification achieved by using a tool or mechanical device. It is essentially the ratio of the output force (the force the machine exerts) to the input force (the force you apply). There are two primary ways to calculate this: and remember: Every machine
