Solution

Mechanical advantage Efficiency
1. Mechanical advantage can be defined as the ratio of the load to effort or it can also be defined as effort arm to the load arm.
1. Efficiency can be defined as the ratio of work output to the work input.
2. The mechanical advantage can be greater than 1, less than 1, or equal to 1.
2. Efficiency is equal to 1 for the ideal machine, or it can be less than 1 in the case of actual machines.
3. Mechanical advantage is not defined in terms of percentage, they are defined in numbers only.
3. Efficiency is defined in terms of percentages and numbers.
