What kind of simple machine is a zip line?
A zip line is a type of simple machine known as a pulley system. It consists of a wheel and axle mechanism that helps to move people or objects along a cable by reducing friction and making it easier to travel between two points.
What is the formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
What is a zip-wire?
A zip-wire is a device that consists of a pulley suspended on a cable, typically made of stainless steel, mounted on a slope. Users can ride the pulley by holding on to it and travelling from one end of the cable to the other, propelled by gravity. It is commonly used for recreational activities and outdoor adventure courses.
A person does 50j of work to lift a crate using a pulley. the pulley's work output is 42j. What is the pully's mechanical efficiency?
The mechanical efficiency of the pulley is calculated as: (Work output / Work input) * 100%. In this case, it would be (42J / 50J) * 100% = 84%. The pulley is 84% efficient at converting input work into output work.
What kind of pulley is a zip line pulley?
A zip line pulley is typically a single pulley with dual wheels to accommodate the cable on both sides. It is designed for high speeds and can support heavy loads as it moves along the zip line cable smoothly.

Is the zip lines part of the normal bus routings?
Zip lines are used to propel someone using a pulley system and a cable line to get them from somewhere high to somewhere low. They are not a part of the bus system.

How old do you have to be to zip line?
It depends on the kind of zip line you go on. I went on a zip line yesterday, and I'm still a kid.
Where can one get a zip line kit?
One can purchase zip line kits from online retailers like Nextag, Amazon, eBay, Zip Line Gear, and Tree House Supplies. One can find tips on installing zip line kits on eHow.

What is zip wiring?
A zip-wire is a pulley system attached to cable or wire, attached to two sturdy objects on an incline, used for transportation or leisure.
Where is the longest zip line located?
The longest zip line is 2,000 meters/ 6,561 feet. The Pronutro zip 2000 is the world's longest zip line. It is located in Sun City South Africa. It descends 918 feet at a speed of 100 mph.
What simple machine is used to move people along the zip line?
simple? gravity.. but since you said machine, I would guess you are referring to the pulley? basically you are offsetting the force of gravity by 'sliding' down the cable.
