Work and also energy room related, due to the fact that energy is always _______ from the object doing the work to the object on which the work-related is done.

You are watching: The efficiency is the number of times a machine multiplies the input force

Since work and energy are __________, power also can it is in calculated—power equals energy divided by time.
Same amount of _______ deserve to be done by using a little force over a long distance as deserve to be done using a large force end a brief distance.
Amount of energy the an equipment transfers to the thing cannot be _______ 보다 the lot of power transferred to the machine.
______ lever—fulcrum is located in between the effort and resistance forces; multiplies and changes direction of force
_________ lever—resistance pressure is located in between the effort force and also fulcrum; always multiplies force
_________ lever—effort pressure is between the resistance force and fulcrum; doesn"t multiply force yet does rise distance end which pressure is applied
Calculating appropriate mechanical benefit (IMA) that a lever—IMA amounts to length that _____ arm split by size of output arm.
Grooved wheel v a rope, simple chain, or cable running follow me the groove is a _______ which is a modified first-class lever.
A <11> sheave is attached come something the doesn"t move; pressure is not multiplied but direction is changed; IMA = 1.

A _______ pulley has actually one end of the rope fixed and also the wheel totally free to move; multiplies force; IMA = 2.
system the pulleys consist of of fixed and movable pulleys; IMA = variety of ropes sustaining resistance weight
