Mechanical advantage

Front

What is mechanical advantage?

Back

Mechanical advantage is the ratio of the output force (load) to the input force (effort) in a machine, indicating how much a machine multiplies force.

How can you increase the mechanical advantage of a lever?

Back

You can increase the mechanical advantage of a lever by moving the fulcrum closer to the load.

What is the formula for calculating mechanical advantage in a pulley system?

Back

The mechanical advantage of a pulley system is calculated by the number of rope segments supporting the load.

Front

If a lever has a mechanical advantage of 5.5 and is used to lift a load of 480 N, what is the input force required?

Back

The input force required is 87.3 N, calculated using the formula: Input Force = Load / Mechanical Advantage.

Front

What is the mechanical advantage of an inclined plane?

Back

The mechanical advantage of an inclined plane is calculated as the ratio of the resistance force (load) to the effort force (input force).

How does a block and tackle system work to lift heavy objects?

Back

A block and tackle system uses multiple pulleys to distribute the weight of the load, effectively reducing the amount of input force needed to lift it.

What is the mechanical advantage of a system with a resistance force of 240 N and an effort force of 100 N?

Back

The mechanical advantage is 2.4, calculated using the formula: MA = Resistance Force / Effort Force.

What role does the fulcrum play in a lever system?

Back

The fulcrum is the pivot point around which the lever rotates, and its position affects the mechanical advantage of the lever.

Front

What is the significance of a mechanical advantage greater than 1?

Back

A mechanical advantage greater than 1 indicates that the machine can lift a load with less input force than the load's weight.

How does the angle of an inclined plane affect its mechanical advantage?

Back

The angle of an inclined plane affects the length of the slope and the effort required; a shallower angle generally increases mechanical advantage.
