The screw shown in the Figure is actually a lever attached to a circular inclined plane. The lever part of these screws is a screwdriver. The distance between screw threads is called pitch and has the symbol P. L is the radius of the screw head surface. The effort is applied at the screw head surface with a turning effect using […]
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 = […]
How to Calculate the Mechanical Advantage of Wheel and Axle?
Answer: Mechanical Advantage of Wheel and Axle = M.A = Radius of the wheel/radius of the axle = R/r.
As R > r, the MA of the wheel and axle is always greater than 1.
The mechanical advantage of an inclined plane is calculated as the ratio of the length of the incline and the height of the incline. It can also be calculated using the value of 1/(sin θ), where θ is the angle of inclination.
In this post, we will talk about the Mechanical advantage formula (MA formula) for different simple machines. Mechanical advantage Formula | MA formula The Mechanical advantage formula (MA formula) can be written as follows: (1) Mechanical Advantage MA = output force/input force (2) Mechanical Advantage MA = resistance force/effort force. The machine uses this resistance […]
The mechanical advantage of a lever is the ratio of the load the lever overcomes and the effort a person or system applies to the lever to overcome some load or resistance. In simple words and as per the formula, it’s the ratio of load and effort. The formula of the mechanical advantage(MA) of a lever […]
