Amachine has a mechanical advantage of 4.5. what force is put out by the machine if the force applied to the machine is 800 n?

a-0.006 n
b-180 n
c-805 n
d-3600 n

The correct answer to the question is D).3600 N.

CALCULATION:

As per the question, the mechanical advantage of the machine MA = 4.5.

The force applied to the machine .

We are asked to calculate the output force of the machine .

Let the output force is denoted as .

The mechanical advantage of a machine is defined as the force amplification of a machine by using certain mechanical devices.

Mathematically it is defined as the ratio of output force to the applied or input force.

Hence, mechanical advantage MA =

Hence, the output force is calculated as -

                                                  [ANS]

Hence, the output force is 3600 N.

i think the answer is a, hope this is right, that would be my best guess.

1/0.14nm = 10^10/1.4 a lot
