R4S8, and there is nothing further that can be done without more information.
The purpose is to reduce the force that must be applied to raise a load. The inclined plane and rollers were used in building the pyramids in Egypt. To raise a body vertically a force must be applied that is equal to the weight of the body. The amount of work done in raising the body is equal to its weigt times the distance through which it is raised. If friction is ignored, the work done using the inclined plane will be exactly equal to the work done in lifting the body directly.

While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane. Overcoming that friction is work done which is totally wasted.While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane.

Stupid question. Millimeters - 1,000 Centimeters - 100 Done.
Gravity does not lift. The force is doing the work by lifting the riders. When the riders come down from the 60 meter height, then gravity will be at work.

You actually can if you know how to do it. I'm not sure how you can do it but my dad says that he has done it before.
lifting heavy objects
This cannot be done. A cubic meter is a volume and a square meter is an area.
First of all its Have you ever DONE the watermelon crawl and 2nd, the watermelon crawl is a fictional thing. it was in a song and is in no way a real "crawl or dance"

No. Lifting weights is an excellent exercise and unless done to excess will not be harmful.
on the side of the road in a pick-up truck, that's how it's done in the south.
it was raised by france
Heavy lifting does not have to lead to lower back pain if done properly. It is also beneficial to do lower back strengthening excerises regularly if one knows that the lifting will be done on a regular basis. It is best to bend down and lift the package as one straightens up to avoid the strain on the lower back.
