To make your pulley machine, tie one end of the rope to the bucket handle and thread the other end through the pulley. You will need another small piece of rope to attach the pulley system to a solid fixture. We do not have any trees, so we used the deck railing. The only thing l...
If you want to transport objects to a higher height or want to test out physics, build an elevator pulley. Pulleys are simple wheels with grooved rims that are pulled by a rope. Pulleys are useful for elevators because they lift more than their weight. The longer the string length, the m...
T hekey was to use a pulley system that would magnify the applied force. So they rigged up atent-shaped scaffold(支架)directly above thetip of the horizontal column, with pulleys(滑轮)suspended from the scaffolds aper(顶点).The idea was that as one end of the column rose, the base ...
A pail with water (mass = {eq}15 \ kg {/eq}) is raised using a pulley system, if the pail accelerates upward at a rate of {eq}1.45 \ m / s^2 {/eq}, how much is the tension on the rope? Newton's...
A simple pulley system using one wheel does not reduce the amount of force, but it does change the direction required to move the load. A compound system, on the other hand, actually reduces the amount of force required to move an object. Compound systems can get complicated. For example,...
When planting in a hanging container, use a plastic pot and install a ratchet pulley system that allows the gardener to easily lower and raise the container by pulling on a cord. Add soil. Always use potting soil in containers; never garden soil. Choose a potting soil that contains organic...

Artwork: How pulleys work#1: With one wheel, a pulley simply reverses the direction of the force you apply. It doesn't alter the force in any other way. Two wheels Now if you add more wheels, and loop the rope around them, you can reduce the effort you need to lift the weight. Su...
Made the chicken door guillotine style with a pulley system so that we can open and close it without going into the house or the yard. Have a roosting rack that folds up with a removable board below it to shunt droppings to a cleanout door, which is at wheelbarrow height for collecting...
