Why do people use pulleys and gears?
People use pulleys to change the direction of a force or to lift heavy objects by distributing the load across multiple ropes. Gears are used to transmit motion and power between two shafts, control speed and torque, and to change the direction of motion. Overall, pulleys and gears help make work easier by utilizing mechanical advantage.
How do gears and pulleys work together?
Gears and pulleys both use rotational motion to transmit power. Gears have toothed wheels that mesh together to transfer torque, while pulleys use belts or ropes running around their circumference to transfer motion. By combining gears and pulleys in a mechanical system, you can achieve different speed and torque ratios to suit specific needs.
How do compound pulleys work?
Compound pulleys work by combining fixed and movable pulleys in a single system to provide a mechanical advantage. The fixed pulleys are attached to a stationary object, while the movable pulleys are attached to the load being lifted. As the rope is pulled, the load is lifted by distributing the weight across multiple pulleys, making it easier to lift heavier objects with less force.
Does a pulley use friction?
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
Why do you use pulleys and gears in your daily lives?
we use pulleys and gears in our daily lives because it would make it easier for people to do our work.We would not have to work so hard.We use pulleys to lift heavy objects.We use gears to build stuff. That's why we see gears in some of our objects.(If you look at a egg beater,you will see gears in a egg beater).
Why do ancient people use pulleys?
Because it made work easier, especially lifting.
Items that use pulleys?

What jobs use combination pulleys?
Tree trimming uses combination pulleys. Also combination pulleys are used to lift engines out of cars to work on them. Some construction sites use them in places they cannot get a crane.

Who works the pulleys in a theatre?
stage hands and people who work behind he scenes.
Why do cars use belts and pulleys?
It transfers power from the alternator to the crankshaft and the camshaft to make your engine work.
