What is Mechanical Advantage (MA)?

Back

Mechanical Advantage (MA) is a measure of the force amplification achieved by using a tool, mechanical device, or machine system. It is calculated as the ratio of the output force to the input force.

What is the formula for calculating Mechanical Advantage for an inclined plane?

Back

The formula for calculating Mechanical Advantage (MA) for an inclined plane is: MA = Slant Length / Stand Height.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help lift or lower objects with less effort.

Front

What is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum, used to lift or move loads.

Front

What is a pulley?

Back

A pulley is a simple machine that consists of a wheel on an axle or shaft that is designed to support movement and change the direction of force.

Front

What is a wedge?

Back

A wedge is a simple machine that is used to separate two objects or portions of an object, or to hold an object in place.

Front

What is the purpose of a screw as a simple machine?

Back

A screw is a simple machine that converts rotational motion into linear motion, often used to hold objects together or lift materials.

How do you convert centimeters to meters?

Back

To convert centimeters to meters, divide the number of centimeters by 100. For example, 20 cm = 20/100 = 0.2 meters.

Front

What is the relationship between the height and slant length of an inclined plane?

Back

The height of an inclined plane is the vertical distance from the base to the top, while the slant length is the distance along the slope. The ratio of these two gives the Mechanical Advantage.

Front

What is a Class 1 lever?

Back

A Class 1 lever has the fulcrum located between the effort and the load, allowing for a balance of forces.
