In a lever, if a load of 10 kN is moved by applying an effort of 1,000 N, what is the mechanical advantage?

In a lever, if a load of 10 kN is moved by applying an effort of 1,000 N, what is the mechanical advantage?

• A. 1
• B. 10
• C. 100
• D. 1,000

Answer: (B)

To determine the mechanical advantage in a lever system, the formula used is: Mechanical Advantage (MA) = Load / Effort. In this scenario, the load is 10 kN (which is equivalent to 10,000 N) and the effort applied is 1,000 N. Plugging these values into the formula gives: MA = 10,000 N / 1,000 N = 10. This means that the mechanical advantage of the lever is 10, indicating that the lever allows the user to move a load that is ten times greater than the effort applied. Understanding mechanical advantage is crucial in power engineering, as it reveals how levers can multiply the force applied, making it easier to lift heavy loads with less effort, which is a fundamental principle used in various mechanical systems and devices.
