Answer:
m = 4
Explanation:
It is given that,
A 100 Newton force applied to a machine lifts a 400 N object.
We need to find the mechanical advantage of this machine.
The mechanical advantage of a machine is given by the ratio of output force to the input force.
Here, output force is 400 N and input force is 100 N
So, mechanical advantage becomes :
[tex]m=\dfrac{400}{100}\\\\m=4[/tex]
So, the mechanical advantage of this machine is 4.
The actual mechanical advantage of this machine will be:
"4".
A force represents a pushing as well as pulling on such material or item caused by its contact with some other thing.
According to the question,
Input force = 100 N
Output force = 400 N
Now,
The mechanical advantage be:
→ m = [tex]\frac{Out. \ force}{Inp. \ force}[/tex]
By substituting the values, we get
= [tex]\frac{400}{100}[/tex]
= 4
Thus the above response is appropriate.
