What is the difference between effort distance and load distance?
chickjenww
How do you measure the effort distance in a lever?
Measure the distance from the fulcrum to the effort?
How well a machine changes effort into work?
Efficiency
Does a machine with an efficiency of 1.2 requires a smaller effort force than a machine that has an efficiency of 2.2?
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
How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
What is the definition of effort distance?
The distance the object moves long the distance.
How did they become involved in the war effort?
How did who become involved with the war effort?
What is the efficiency of the pulley system?
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.

Efficiency
What does efficiency gains mean?
efficiency meansThe ratio of the output to the input of any systemskillfulness in avoidingwasted time and effort; "she did the work with great efficiency.

If the effort distance is increased by an inclined plane will the effort force decrease?
actually, the effort force would be decreasing, and the effort distance would be increasing!
How does the position of the fulcrum and the location of the load affect the amount of effort force you must exert to lift the load?
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.
What is the formula to calculate effort?
no, you cannot calculate effort for effort is not an equation its is just how much force you apply on an object their is no way to show the formula for effort their is no formula for effort no you're wrong you don't even know which there you are suppose to use so how do you know the answer you probally guest.
