The roadies at a music concert have to get a piano weighing 2500 N onto a stage 1.5 m high. They have a 6 m-long ramp.Calculate the ideal mechanical advantage of the ramp.With the piano on a small trolley they have to exert 700 N force to push it up the ramp. Determine the actual mechanical advantage of the ramp.Is the actual mechanical advantage greater than, less than, or the same as the ideal mechanical advantage? Explain why this would be.In a world with no friction, calculate the effort force the roadies would need to apply to get the piano up the ramp.Note: Show your calculations.

A teenager on a skateboard has a weight of 400 N. They can ride up a straight skateboard ramp with an effort force of 50 N.Calculate the mechanical advantage provided by the skate ramp.

Find the force needed to lift a 2,000 N weight using a machine with a mechanical advantage of 15.
