If the out put force is less than the input force of a simple machine the mechanical advantage is less that one?

If ur asking true or false..its false

Yes, if the output force is less than the input force the mechanical advantage is less than one.

Explanation:

The mechanical advantage is the ratio of the output force to the input force. It tells the degree to which the machine achieves its aim of using less effort to overcome a large load.

If the input force is greater than the output force, it implies that the effort applied is greater than the load. Hence the mechanical advantage is less than 1.

the product of the pressure and volume is also constant

let that person have a turn to speak : )
