Question

a second class lever always has an ideal mechanical advantage less than 1. true false

Explanation:

The ideal mechanical advantage (IMA) of a second - class lever is calculated as \(IMA=\frac{\text{length of effort arm}}{\text{length of resistance arm}}\). In a second - class lever, the effort arm is always longer than the resistance arm. So, \(IMA> 1\).

Answer:

FALSE
