A lever has a 6-foot effort arm and a 2-foot load arm. What is the mechanical advantage?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

3

  1. A 4
  2. B 1
  3. C 2
  4. D 3

Why this is the answer

MA (lever) = effort arm ÷ load arm = 6 ÷ 2 = 3. A mechanical advantage of 3 means 1 pound of effort lifts 3 pounds of load.

About this topic: Simple Machines (Levers, Pulleys, Gears)

Simple machines — levers, pulleys, gears, inclined planes, wheel-and-axle, screws — are the heart of Mechanical Comprehension. Each question comes down to mechanical advantage: how much the machine multiplies force, and the trade-off in distance. This is one of 23 Mechanical Comprehension questions on simple machines (levers, pulleys, gears), each with a full explanation on a single study page.
