How can a lever increase the force applied without changing the amount of work being done?
Work is force times distance. A lever will increase force, at the cost of distance, or it will increase distance, at the cost of force. Each of these is inversely proportional, so the net force times distance is the same. Said in other words, a lever cannot add to or subtract from work - work is the same in all cases.
Why is work input equal to the effort force times the effort distance?
That's the definition of "work" ... (force exerted) times (distance through which the force acts). If you push against the end of a lever with a force 'F' and move it through a distance 'D', then (F x D) is the work you put into the lever.
If the effort force for lever is 50 Newtons then what would be the resistance force Assme no friction IMAAMA?
the resistence force will be equal to 50 Newtons times the distance from the point of the effort force to the object along the lever.
How is the work done on each part of a lever equal even though the distance and force is different?
Work = (force) times (distance) The forces on the two ends of the lever are different, and so are the distances that the ends of the lever move through. But they're different in exactly the right way so that their product (force x distance) is the same on both ends, and the work is that product.
How a lever can increase the force applied without changing the amount of work being done?
Levers are used in everyday life. The force is a lot to do with pivots and moments e.g. a wheelbarrow- the effort force pushes down on the handle (lever) the load is pulled down by gravity and the pivot is the front wheel. So a lever changes force by the chemical energy in your muscles aiding or fighting gravity. Hope this helps x
How does force affect distance?
Assuming you mean the force of gravity. As the distance increases, the force of gravity is reduced exponentially. Double the distance between two bodies, the gravitational force is reduced four times.
Why does second class levers have a mechanical advantage greater than one?
Why a third class lever cannot magnify force
What is law of lever?
If the distance from the handle to the pivot (fulcrum) is n times the distance from the load to the pivot, then the force required to move the load will be the weight of the load divided by n,
What is the law of lever?
If the distance from the handle to the pivot (fulcrum) is n times the distance from the load to the pivot, then the force required to move the load will be the weight of the load divided by n,
What is the benefit of a lever?
A lever allows you to magnify the force applied to an object at the expense of distance. With a lever you can move objects many times larger than you could without one, but at a slower pace.
What is force times distance equals?
Force times distance equals work.
What does work equals force times?
Force times Distance equals Work
