Question

what output force is generated when an input force of 630 n is applied to a machine with a mechanical advantage of 3

Answer 1

Answer : Output force is 1890 N.

Explanation :

Given that,

Input force is 630 N

Mechanical advantage is 3

Mechanical advantage of a machine is defined as the ratio of output force and the input force.

Mathematically it can be written as :

$m=\dfrac{F_o}{F_i}$

Where,

$F_o$ is the output force

$F_i$ is the input force

So, $3=\dfrac{F_o}{630\ N}$

$F_o=1890\ N$

Hence, this is the required solution.

Answer 2

The mechanical advantage is the factor by which
the machine multiplies the input force.

If the MA is 3 and the input force is 630N, then
the output force is

           (3) x (630N) = 1,890N
