How do pulleys change the direction and amount of force?
Pulleys change the direction of the force applied by redirecting it along a different path. By using multiple pulleys in a system, the amount of force required to lift an object can be reduced, making it easier to lift heavy loads.
How does the force required to raise a load change when the number of pulleys is changed?
The force required to raise a load decreases as the number of pulleys increases. This is due to the mechanical advantage gained from multiple pulleys, which reduces the amount of force needed to lift the load. The more pulleys there are in the system, the greater the reduction in force required.
What pulleys are attached to an overhead structure and change the direction of force?
A block and tackle system with multiple pulleys is typically attached to an overhead structure to change the direction of force. The pulleys allow for lifting or moving heavy objects with less effort by distributing the load across multiple ropes and changing the direction of the force applied.
What are the three different types of pulleys?
The three types of pulleys are fixed pulleys, movable (or movable) pulleys, and compound pulleys. Fixed pulleys change the direction of the force applied, movable pulleys provide a mechanical advantage by reducing the force needed, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.
What are the three kinds of pulleys and describe each briefly?
The three kinds of pulleys are fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are anchored in place and change the direction of the force applied. Movable pulleys have a pulley that moves with the load, reducing the force needed to lift the object. Compound pulleys consist of multiple pulleys working together to provide mechanical advantage in lifting heavy loads.
How can pulleys change direction of the force?
yes
What do fixed pulleys always do?

What ways can machine change the direction of the force?
pulleys, levers, pendulums

What is the 2 kind of pulley?
The two kinds of pulleys are fixed pulleys and movable pulleys. Fixed pulleys are stationary and change the direction of the force applied, while movable pulleys have a free end that moves and both change the direction of the force and provide a mechanical advantage.
How is IMA determined for pulleys?
IMA for pulleys is the resistance force divided by the effort force.
