The ideal mechanical advantage (IMA) of the pulley system is calculated by the formula IMA = distance output / distance input. In this case, the distance output is 2.0 m (the distance the engine is lifted), and the distance input is 8.0 m (the distance the force must move). Therefore, the IMA of the system is 2.0 / 8.0 = 0.25.
Friction reduces the mechanical advantage (IMA) of a simple machine by causing energy losses in the form of heat. As friction increases, the effectiveness of the machine in transmitting force or lift decreases, ultimately lowering the mechanical advantage.
The ideal mechanical advantage (IMA) of a ramp with a greater height will be higher compared to a ramp with a shorter height. This is because the IMA is calculated by dividing the length of the ramp by the height, meaning a higher height will result in a larger IMA.
The ideal mechanical advantage (IMA) of an inclined plane is calculated by dividing the length of the plane by the height. In this case, the IMA would be 8m (length) divided by 2m (height) which equals an IMA of 4.

IMA and AMA are unitless
the IMA is the ideal mechanical advantage.
Ima means mom or mommy.
Increase the IMA
To do this you first have to calculate your ideal mechanical advantage (IMA). The IMA is equal to the effort distance (the distance from the fulcrum to where you will apply the effort) divided by the load distance (the distance from the fulcrum to the load). You can then set your IMA equal to your acutal mechanical advatage (AMA) which assumes 100% efficiency. The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your load force is 500 lbs: 5=500/effort force. Therefore the effort force would be 100 pounds.
