what output force is generated when an input force of 630 n is applied to a machine with a mechanical advantage of 3
2 answers:
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 :
Where,
is the output force
is the input force
So,
Hence, this is the required solution.

The fact that the layers of graphite are held together by only weak Van der Walls forces implies that they can slide over each other.
<h3>Why is graphite a solid lubricant?</h3>We know that graphite is composed of layers. These hexagonal layers are held together by weak Van Der Walls forces and as such are able to slide over each other. The carbon atom in each layer are held together by strong covalent bonds.
The fact that the layers of graphite are held together by only weak Van der Walls forces implies that they can slide over each other and as such make the graphite fluid.
Thus, the image that shows these layers of graphite is attached to this an answer
