What are the main parts of a pulley?

Back

The main parts of a pulley include the wheel, axle, groove, and rope.

What is the function of the wheel in a pulley system?

Back

The wheel allows the rope to move smoothly and helps in changing the direction of the force applied.

Front

What is the function of the rope in a pulley system?

Back

The rope transmits the force applied to lift or move an object.

Front

What is the ideal mechanical advantage (IMA) of a pulley?

Back

The ideal mechanical advantage of a pulley is the ratio of the load force to the effort force, indicating how much the pulley system multiplies the input force.

Front

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

Back

The ideal mechanical advantage of a single fixed pulley is 1.

Front

What is the ideal mechanical advantage of a movable pulley?

Back

The ideal mechanical advantage of a movable pulley is 2.

Front

What is a compound pulley system?

Back

A compound pulley system combines fixed and movable pulleys to increase the mechanical advantage.

Front

What is the difference between a fixed pulley and a movable pulley?

Back

A fixed pulley is attached to a structure and does not move with the load, while a movable pulley moves with the load, providing greater mechanical advantage.

Can a ladder be considered a pulley system?

Back

No, a ladder is not a pulley system; it is a simple tool used for climbing.
