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 – Many machines make use of gears. Gears can be used to increase or decrease the rotational effects of a force.
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 = […]
