The mechanical advantage.
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.

A mechanical advantage occurs when a tool such as a hammer is used that increases the amount of force being applied without increasing the effort of the person using the tool. To increase mechanical advantage, you could use a bigger hammer to increase output force.
Mechanical Advantage=1
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.

One.Since the question clearly states that the machine only changes the direction there can be no mechanical advantage gained.In order for a machine to have a mechanical advantage greater than 1, the machine must be able to change two or more of these factors:The amount of force exertedThe distance over which the force is exertedThe direction over which the force is exerted
The mechanical advantage of the machine is"if you give small accelration , it will increase the speed of the engine... It is possible by mechanical
Efficiency of a machine or mechanical advantage
it is less than the ideal mechanical advantage
775 is a number, not a machine. It, therefore, has no mechanical advantage.

There are three types of levers namely first, second and third class. First class levers can change the direction of input force.
The mechanical advantage is 5.Mechanical Advantage = Output Force/Input Force
