Lever questions are often found in mechanical aptitude tests. Gaining basic knowledge of levers can be made through our study guide: it’s easy and will help you score higher in your mechanical aptitude test.
A lever is a simple machine, which provides a mechanical advantage in carrying loads. It comprises of a fulcrum, which is a hinge or a pivot, and a beam or a rigid rod. Two forces are applied onto the beam: the effort and the load.
The extent of the mechanical advantage depends on the torques created on both sides of the beam. A torque is the product of the force and the arm’s distance.
Levers are divided to three classes, where the above is a short example of a first class lever. More about these levers, as well as second- and third-class levers, is broadly discussed in our full study guide.
Usually, you will be required to distinguish which of the torques (input or output) is larger, or determine the direction of the lever’s tilt. In some cases, you will be required to perform light calculations.
A basic lever question may be:
By which lever would it take less effort to lift the load?
