Question

A machine has mechanical advantage 2, what does it mean?

Answer 1

Answer:

Mechanical advantage is the measure of the force amplification achieved by using a tool , mechanical device or machine .

The mechanical advantage of a machine is 2. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 2 means that for example if you apply 100 N then your machine will multiply that force and generate 200 N.

hope it helps!

plz mark me as brainliest!

Explanation:

Answer 2

Answer:

• Mechanical advantage is a ratio of output force to input force in a system that may be used to study forces in simple machines such as levers and pulleys.

• Clearly stated, it puts out twice as much force as it takes in  but there's a catch: the input force has to go twice much further. 

• So example, if the weight you lift is half as far from the pivot as your hand pressing on it, you may raise twice as much weight  but only half as far as you move your end of the lever.
