Mechanical Advantage of a Lever
Mechanical Advantage of Pulley
Lead Screw Mechanical Advantage
Wedge Mechanical Advantage
Mechanical Advantage of Ramp(Inclined Plane)
Wheel and Axle Mechanical Advantage
Mechanical advantage is nothing but the division of output force to input force. Here we can get the formulas of 6 simple machines they are screw, wedge, ramp, lever, pulley, wheel and axle.
MA = Output force/ input force
The point where we can apply input force is called the effort.
The point that remains stationary is a fulcrum.
Resistance is the load.
Mechanical Advantage = effort arm/load arm
It is a simple machine made up of wheels and ropes. Two wheels make one pulley.
Mecahnical Advantage = 2 * n
Here, n is the number of pulleys connected to the object.
A screw has a threaded cylindrical shaft and a head.
MA = π * diameter of the screw shaft / lead of the thread.
A wedge is a triangle shape and is used to lift heavy objects or split the object into two parts.
MA = thickness/length
thickness is measured in a horizontal direction.
Length is measured in the vertical direction.
The ramp is a flat surface inclined at an angle to the horizontal.
MA = L/V
MA = 1/sinθ
Where L is the ramp length
V is the ramp height
θ is the angle between the slant length and horizontal line.
Wheel and Axle:
A wheel and axle is a machine having two parts. BY applying a small force to the wheel on the outside, it will be transformed to the smaller axle and amplified.
MA = Wheel radius / axle radius
Question: Estimate the mechanical advantage if 250 N force is needed to overcome the load of 600 N.
input force = 250 N
output force = 600 N
Mechanical Advantage = output force/input force
Therefore, the mechanical advantage is 2.4

1. What is meant by mechanical advantage?
Mechanical advatange is nothing but the advantage gained by using a machanism of transmitting force. It measure the force amplification achieved using a mechine system or mechanical device.
2. How to Calculate Mechanical Advantage?
Mechanical advantage is the ratio of output force to the input force. Substitute the values in the formula and divide them to get the MA value.
3. What are the formulas of mechanical advantage?
Mechanical advantage is used to analyze forces in various simple machines like lever, pulley, screw, wedge, ramp, wheel and axle. Their formulas are lever MA = effort arm/load arm, pulley MA = 2 * number of pulleys, screw MA = π * diameter/lead, Wedge MA = wedge length/wedge thickness, ramp MA = ramp length / ramp height, Wheel and axle mA = wheel radius / axle radius.
4. What is the mechanical disadvantage?
If a lever's load arm is longer than its effort arm, then it is called mechanical disadvantage. It has a low load force to effort ratio.
