Pulley Flashcard

Front

What is a fixed pulley?

Back

A fixed pulley is a type of pulley that is anchored in a fixed position and does not move with the load. It changes the direction of the force applied.

Front

What is a movable pulley?

Back

A movable pulley is a type of pulley that moves with the load. It allows for a mechanical advantage, making it easier to lift heavy objects.

Front

What is a compound pulley?

Back

A compound pulley is a system that combines both fixed and movable pulleys to increase mechanical advantage and reduce the effort needed to lift a load.

Front

What is a swivel pulley?

Back

A swivel pulley is a type of pulley that can rotate around a central point, allowing for more flexibility in the direction of the load.

Front

What is the primary use of a pulley?

Back

A pulley is primarily used to lift heavy objects to tall heights by changing the direction of the force applied.

Front

What is mechanical advantage in pulleys?

Back

Mechanical advantage is the ratio of the load force to the effort force in a pulley system, indicating how much easier it is to lift a load.

Front

How do you calculate the ideal mechanical advantage of a pulley system?

Back

The ideal mechanical advantage (IMA) of a pulley system is calculated by counting the number of rope segments supporting the load.

Front

What is the difference between fixed and movable pulleys?

Back

Fixed pulleys do not move with the load and only change the direction of the force, while movable pulleys move with the load and provide a mechanical advantage.

Front

What is an example of a real-world application of pulleys?

Back

An example of a real-world application of pulleys is a construction crane, which uses pulleys to lift heavy materials to great heights.

Front

What is the formula for calculating the ideal mechanical advantage of a compound pulley?

Back

The formula for calculating the ideal mechanical advantage of a compound pulley is the total number of rope segments supporting the load.
