WHY IS MOVEABLE PULLEY MORE USEFUL THAN FIXED PULLEY?
A moveable pulley is more useful than a fixed pulley because it allows for a mechanical advantage, making it easier to lift heavy loads. With a moveable pulley, the effort force is reduced as the load force is distributed between the two sections of the rope supporting the load. This results in less force required to lift the load compared to using a fixed pulley.
What is the mechanical advantage of a single fixed pulley?
Thew pulley changes the direction of the effort force.
Can a pulley hang up clothes?
Yes, a pulley system can be used to hang up clothes by attaching the clothesline to the pulley and using it to raise or lower the clothes. This can be particularly useful for hanging clothes in a high or hard-to-reach area.
Why is pulley useful?
A pulley is useful because it allows for the redirection of force and makes it easier to lift heavy objects by distributing the load over multiple ropes. It also can change the direction of the force applied to move an object. Pulleys are commonly used in various systems such as elevators, construction equipment, and exercise machines.
What is the efficiency of a pulley if 25 percent of the energy applied to the system is converted to heat?
The efficiency of the pulley system is 75% if 25% of the energy is lost as heat. This means that 75% of the input energy is used to do useful work, while the remaining 25% is lost as heat.

What simple machine would be useful to get supplies up to a tree house?
Use a pulley and a rope and a flat piece of wood or a bucket:)
How is a fixed pulley useful?
A fixed pulley changes the direction of a force, making it easier to lift objects vertically by allowing you to pull down instead of up. It does not provide any mechanical advantage in terms of reducing the amount of force needed to lift the load.
What is the efficiency of a pulley if 25 percent of the energy applied to the system is converted to heat?
The efficiency of the pulley system is 75% if 25% of the energy is lost as heat. This means that 75% of the input energy is used to do useful work, while the remaining 25% is lost as heat.
What force is overcome when a pulley is used?
A simple pulley is a rope (or chain or belt) with one wheel this may be a class 1 or class 2 pulley.For a class 1 pulley, the pulley stationary and the force applied to the rope is in the opposite direction as the movement of the object.For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.
How are simple machines useful to a man?
every single thing in existence to this day has atleast on simple machine used in it. wether this is the screw, wedge, pulley, etc.
What is the name of the pulley on a 1997 dodge stratus 2.5 V6?
There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
