Question

Which is the result of using a machine?

A) The mechanical average makes the work output greater than the work input?
B) the machine can put out Force without having Force applied to it
C) A large force can be exerted through a long distance to have a small force exerted through a small force
D) a large force can be exerted through a short distance to have a small force exerted through a long distance

Answer 1

the answer is d just took the test on edge.

Step-by-step explanation:

Answer 2

Correct Answers is A.

The machines gives us some mechanical advantage. This means the mechanical average makes the work output greater than the work input
Simple most example is a lever. The force applied is smaller and the output work is larger as compared to input.

Option B cannot be true, as there must be a force to get some work done.
Option C and D are inverse of what a machine is designed for. A small force can be exerted through a large distance to have a large force exerted through a small distance. Common Example of this principle is a screw opener.
