∙ 6y agowork = force x distance = 180 joules; force = 180/.8 =225 Newtons

How much force exert when lifting an object?
a force of depend on mass
How can pulleys be used to reduce the force in lifting up an object?
They convert distance into force. So putting a pulley on a load would result in you having to haul up twice as much rope, but lifting about half of the weight of the load. Multiple pulleys increase rope length and further decrease force required to move the load.
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.
A force of 10000 N is applied to a stationary wall How much work is performed?
W=(10,000N)(Om)
How much work is performed when 100 kg crate is pushed 30 meters with a force of 40 newtons?
Multiply the force by the distance. The mass is irrelevant for this problem.
How much force exert when lifting an object?
a force of depend on mass
How much force does one exert when lifting an object?
The force would be the weight of the object.
What device is used for lifting heavy weights by the application of a much smaller force?
hydraulic ram
What is the function of a jackscrew?
Using mechanical advantage to offer a large lifting force from a much smaller input force, essentially an inclined plane or wedge.
How much was a Mailman salary in 1970?
He most likely made around 4 to 5 dollars an hour.
Measurement of how much a machine multiplies force or distance is called?
Measurement of how much a machine multiplies force or distance is called mechanical advantage. An example of this mechanism would be a crane, which allows the lifting of heavier objects with less force applied.
What minimum downward force needed to lift the 120 Newtons weight?
No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
How can pulleys be used to reduce the force in lifting up an object?
They convert distance into force. So putting a pulley on a load would result in you having to haul up twice as much rope, but lifting about half of the weight of the load. Multiple pulleys increase rope length and further decrease force required to move the load.
What do you need to know to find out how much work you do when you pick up a cat?
Work is equal to force x distance. So it will depend on how much force you apply to lifting the cat, and also how far off the ground you lift it.
