Concept explainers
Distinguish between theoretical mechanical advantage and actual mechanical advantage. How would these compare if a machine were 100% efficient?
To explain: The difference between theoretical and actual mechanical advantage.
To compare: Atheoretical and actual mechanical advantage if a machine were 100% efficient.
Explanation of Solution
Introduction:
Energy always convertsfrom one form to another form. It can neither be created nor destroyed.
Theoretical mechanical advantage is a theoretical concept. In this thermal energy gets converted into mechanical energy. All energy gets converted without any loss of energy due to heat or friction.
Actual mechanical advantage is a practical concept. In this, thermal energy is converted to mechanical energy along with losses. Friction is considered as anactual mechanical advantage. There isa loss of energy due to heat and friction.
If machine is 100% efficient then output of both will same. This means that both machines are identical.
