The ideal mechanical advantage (IMA), is a type of mechanical advantage of a device with the assumption that its components do not flex, there is no friction and no wear for Ideal Mechanical Advantages. It is calculated that using the physical dimensions of the define and defines the maximum performance the device can achieve. This can be calculated by finding the ratio between the distance over which input force has exerted on the machine and the output force that has been exerted on the object.
Differences of mechanical advantage:
The Ideal Mechanical Advantage and the Mechanical Advantage are different because Ideal Mechanical Advantage is about finding Newtons and Mechanical Advantage is about finding distances, another reason for why the are different is because Mechanical Advantage includes friction while the Ideal Mechanical Advantage does not have friction. An Ideal Mechanical Advantage that is close to the Ideal Mechanical Advantage is a lever because there is not much friction and a ramp is not close due to friction.
How to increase Efficiency:
For any machine the efficiency is always less than a 100% because input work that is used compensates for work that is done by friction.
