Efficiency is calculated by dividing the work output by the work input. In this case, the work output is the work done against gravity, which is 2000 N * 1m = 2000 J. Thus, the efficiency is 2000 J (work output) / 3000 J (work input) = 2/3 = 66.7%.
The efficiency of a wedge is calculated by dividing the load distance by the effort distance, then multiplying the result by 100 to get a percentage. The formula is: Efficiency = (load distance / effort distance) x 100. This gives you the ratio of the load distance to the effort distance, indicating how efficiently the wedge can lift or separate objects.
The distance of effort is the distance along the incline plane that you apply force to lift the car. The distance of resistance is the vertical distance that the car is being lifted. In this scenario, the distance of effort is the 4 meters along the incline plane, and the distance of resistance is the vertical height the car is lifted.

The distance the rope needs to be pulled to lift the load can be calculated using the formula: Distance = (Load weight * Pulley system efficiency) / Effort force applied Efficiency of the pulley system depends on the number of ropes supporting the load. The effort force applied is the force needed to lift the load.
The formula to calculate effort distance in mechanical advantage is Effort Distance = Load Distance / Mechanical Advantage. This means that effort distance is the distance over which the effort force is applied to move the load in a machine.

How did who become involved with the war effort?
The formula to calculate effort distance in mechanical advantage is Effort Distance = Load Distance / Mechanical Advantage. This means that effort distance is the distance over which the effort force is applied to move the load in a machine.
The effort distance in a lever is measured from the point where the effort force is applied to the fulcrum. It is the distance over which the effort force acts to move the lever. By measuring this distance, you can calculate the mechanical advantage of the lever.
Efficiency is a measure of power losses. A machine with an efficiency of say 85% or 0.85, experiences 15% power losses from input to output (as heat through friction) This would be typical for say a car, comparing crankshaft power to power at the drive wheels. No machine will exceed 100% efficiency > Work done = force * distance Efficiency = work done at output / work done at input > Mechanical Advantage (leverage) is distance moved by input / distance moved by output. Output force = input force * Mechanical Advantage
increasing the distance
If the pulley is frictionless the angle does not matter, the tension in the rope will be the same on both sides of the pulley. If there is friction in the pulley however then you want to reduce the friction as much as possible. You do that by creating as large an angle between the two ropes as possible.
actually, the effort force would be decreasing, and the effort distance would be increasing!
