Efficiency Efficiency
Inceases its efficiency.
A very practical example of mechanical advantage is the use of a "cheater bar." If you find a bolt that is hard to break, simply slip a long pipe or similar object over the handle and it will apply much more torque.
Deceasing friction increases efficiency and reduces heat loss.
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
Efficiency Efficiency
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
Friction is the reason that you can never have a 100% efficient machine. It is the reason that most machine have horrible efficiency.

Polishing the surface or coating it with a lubricant is a way of reducing friction. To increase friction just hammer some ridges on the surface.
You can increase your purchase efficiency by reducing the amount of dead stock or slow moving inventory items. This will lower your total inventory value, increasing purchase efficiency. "Stock Items Only Of Which You Have Need"
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
Winglets increase an aircraft's operating efficiency by reducing induced drag at the tips of the wings
By reducing the coefficient of friction between the brakes and the wheel OR between the road and the wheels.
