What are Examples of 1st, 2nd, and 3rd Class Levers?

Answer: A simple mechanism with a fulcrum and a rigid beam is what a lever consists of. The load (output force) and effort (input force) are exerted on either end of the beam. The fulcrum is the pivot point of the beam. A weight is applied to the other end of the lever when exertion is given to one end of the lever. This will cause a mass to rise. The amount of force required to rotate an object about its axial point is torque (or pivot point).

First-Class Lever

The fulcrum of this kind of lever is positioned between the weight and the force exerted. The force-fulcrum-weight order is used to represent it. It is the most basic form of lever. 

Example

  • Seesaws, crowbars, or our hands pressing an object
  • A wheel and axle is the example
  • Also, pulling a nail from a hardwood plank is a first-class lever

Second-Class Lever

The fulcrum is basically at one end, while the force is applied at the other. The weight is in the centre of these two options. 

Examples

  • Wheelbarrow
  • Staplers 
  • Openers for bottles
  • Nutcrackers

Third-Class Lever

At one end of the lever, the pressure is delivered in the centre, and the weight is at the opposite end. 

Examples

  • Rod for fishing
  • A floor-sweeping tool
  • A bat is used in baseball.
  • An arrow and a bow
  • The jaw of a human
