∙ 7y agoThe answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.

to balance moment 10 feet x force = 2 feet x 200 force = 40 pounds
vertical lift versus slope the work done is the same (force * distance), but with a say 30 degree slope you need only half the force but need to travel twice as far to raise the load the same height vertically
Lift lbf = (Normal force lbf) x (cosine of angle of attack)
Lift
Yes, work is being done when you lift a box against the force of gravity. Work is defined as the force applied over a distance, and in this case, the force you exert to lift the box is acting over a vertical distance, thus work is being done.

You exert a force of 30 N.
The force that you exert on a lever can be called the effort force. The lever has three parts. They are: the fulcrum, the load, and the effort force. This can also be classified as the input force. The force that you exert to perform a task is known as the input force.
A minimum of 1.667 newtons.
An airfoil can exert lift, drag, and thrust forces. Lift force is generated perpendicular to the airflow and is essential for providing the upward force needed for an aircraft to stay aloft. Drag force acts opposite to the direction of motion and resists the aircraft's movement. Thrust force is generated by the aircraft's engines and propels the aircraft forward.
A ramp reduces the force needed to lift a heavier object by allowing you to exert that force over a longer distance. This results in less work being done for the same overall force, making it easier to move the object.

Yes, work is done when you lift a brick against gravity because you are exerting a force over a distance in the direction of the force of gravity. Work is defined as force multiplied by distance in the direction of the force, so lifting the brick requires work to be done.
Levers help you to exert a force to move an object by increasing the efficiency of your effort. They allow you to lift, push, or pull heavy objects with less force than if you were to directly lift them without a lever.
The distance is longer than the lift or the drop, but the force you need is less than the weight of the load.
