Answer:
Yes, if the output force is less than the input force the mechanical advantage is less than one.
Step-by-step 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.
