the work performed is the weight of the block times the height, or rise, of the incline
No. On a horizontal surface the normal force is equal to weight. If you are moving at constant velocity you only overcome frictional force, which is not equal to weight. This is easier to see on an incline. At some point an object will slide at constant velocity down the incline. This is related to trig functions of the angle of incline multiplied by the weight which is always less than the weight.
The counter-weight serves to balance the crane when it's lifting anything. If there was no counter-weight, the crane would topple over !
The suitable weight for an elevator counterweight is equal to the weight of the elevator itself. This ensures that the elevator moves smoothly and safely without any jerking or swaying. ESCON Elevators use high-quality counterweights that are perfectly balanced, ensuring a smooth and comfortable ride for every passenger.
To counteract the weight of the barricades arm. This way the counter weight will do most of the work when the barricade is lifted.
the work performed is the weight of the block times the height, or rise, of the incline
An incline does not have a weight associated with it.
The answer depends on a number of factors: - the weight of the car - the steepness of the incline - the frictions of the of both the car to the incline surface and the pusher to the incline surface

The best way to carry the load is backwards and with the forks up. When you put the forks up, you will shift the weight of the load towards the middle.
The E4 Elliptical Cross Trainer could be used on an incline as long you keep proper posture. On an incline your weight is kind of shifted and it could be more difficult, but other than that, it should work.

it depend on your weight the incline and the height of you.

Yes, if the incline angle becomes great enough. > As the angle increases, the force on the object down the incline increases but the effective weight on the slope surface decreases. > When the object breaks away the angle of incline can be used to calculate the coefficient of friction between the two surfaces. > coefficient of friction = sine ( incline angle ) / cosine ( incline angle )
because cranes have a counter weight that should weigh more than whatever they are carrying
Yes it would. Speed will depend on Weight of the ball, Incline angle, Friction, and air pressure.
