All three classes of levers make work easier, but they do so in different ways. In this post, we will discuss a few distinguishing pointers of three types of levers. And, these pointers will help to compare three classes of levers structurally and functionally. Compare levers belonging to three classes – In a first-class lever, […]

## Gear as a simple machine

A gear is a wheel and axle with the wheel having teeth around its rim. When the teeth of two gears interlock, the turning of one gear causes the other gear to turn. features of a gear When two gears of different sizes are interlocked, they rotate at different rates. Each rotation of the larger […]

## How to Calculate the Mechanical Advantage of a Wedge – formula

A wedge is a simple tool in the shape of a triangle. In other words, a wedge is simply two inclined planes back to back. Figure 1 shows the simple formulas for calculating the IMAs of these machines. The mechanical advantage formula for a wedge is dependent on its geometry: IMA = L/t MA of a wedge = […]
