Question

what is meant by statement that the MA ofa simple machine is 3





























​

Answer 1

Answer:

Explanation:

r: The work done in the machine is called is called input work and the work done by the machine is called output work. Velocity ratio of a lever is 3 means distance travelled by effort is 3 times the distance travelled by the load

Answer 2

Answer:

It means that we have to apply apply 3 times less effort to lift the load.

Explanation:

We know that, the ratio of the load to the effort in a simple machine is called mechanical advantage. Hence, if we apply, for example in this situation, 100 N of force then the machine will multiply the force and generate 400 N, thus, reducing the required amount of effort by 3 times.
