If you lift two loads up one story how much work do you do compared to lifting just one load up one story?
The work done by lifting two loads up one story vs the work done lifting one load will depend on the weight of the second load. If it is the same as the first load, it would simply be twice the work to lift. Work is described as a force times a distance and a force is described as a mass times an acceleration. In this case, the force would be twice as much, so the work would be as well.
What is actual mechanical advantage in physics?
The ratio of the force required to do work without the machine (load force, FL) over the force required to do work when using a machine (effort force, FE).
When do you say that work is done?
work is only said to be done when force applied to a load moves through a distance.that is to say that a man standing one place carry a load without moving for 5 hours have not done any work.
How much work is done in lifting a 300-lb load of bricks to a height of 60 feet on a building under construction?
Work = (force) x (distance) (300 poundforce) x (60-ft) = 18,000 foot-pounds
How a first class lever works?
the fulcrum lies between the effort and load the effort or force and makes it possible to perform the work
How do you find the effort force if you already have the load force and the distance moved by load force?
work (effort) equals load times distance

What is work done by a coolie walking on a horizontal platform with a load on his head?
The displacement of the load is perpendicular to the direction of force therefore work done by the coolie against the force of gravity is zero.
How does a simple machine make a hand brake work?
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. They can be used to increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the force.
What is actual mechanical advantage in physics?
The ratio of the force required to do work without the machine (load force, FL) over the force required to do work when using a machine (effort force, FE).
What is dependancy load?
Dependency Load is a portion of the population that is not in the work force; Total people under 14 and over 65.
A fulcrum is on the left side of a board as it is moved to the right will the force be the same?
Work: The work done by the force is the same as the work done on the load in an ideal simple machine.
How does input force output orce and load force work together in a lever?
because if there wasn't an input force, or any one of those, the machine would not work properly
Work is done only if?
Work is done if a force moves through a distance. Eg Someone standing carrying a heavy load is not considered to doing work unless the load is moved
How much work is done when a force of 50.0 lb is used to push a box 10.0 ft across a level floor?
That completely depends on your own efficiency of motion. The only work you do is whatever it takes to operate your muscles and limbs. Moving a load horizontally doesn't add energy to the load, so the effective 'industrial' work is zero.
Does a lever do as much work on the load as you do on the lever?
yes, because when we pull or push the lever it applies the same force as applied by us and then after the same displacement occours.
Why the coolie carrying load in the head is not doing any work scientificall?
it is because the displacement of load being horizontal,is normal to the direction of force of gravity ie.,cos 90' which is zero but he surely does some work if we consider it against the force of friction.
