How do you use a rope pulley?
Attach the rope first to the bottom of the upper fixed pulley, then loop the rope down through the wheel on the moveable lower pulley. Now, loop the rope back up through the top fixed pulley. Make sure the rope is fully seated into the grooves on the pulley wheels.
How does pulley make work easier?
A pulley system makes it easier to lift an object than lifting the dead weight by hand. A single pulley essentially changes the direction of the pull or force applied. When a person uses two or more pulleys in a system, then the system also multiplies the force applied besides changing its direction.
Where does rope attach to extension ladder?
A rope exists on most for adjusting the ladder while it is place. This is attached to the bottom rung of the fixed ladder and passed through a pulley at the top of the movable ladder. This rope is protected by a thimble where it is attached to the bottom rung to protect it from wear.
Can you lift yourself up with a pulley?
Absolutely! Just like rowing a boat, the force you apply to move just needs to be stronger than any resisting forces. In this case, the resisting force is your weight. A pulley allows you to lift heavier objects, effectively lightening the load.
