Question

The Great Pyramid is 146m high. How long is a ramp from the top of the pyramid to the ground that has a mechanical advantage of 4?

Please give equation.

Answer 1

To find the length of the ramp, we can use the equation for mechanical advantage (MA), which is:

MA = load / effort

The mechanical advantage of the ramp is 4, which means that for every 4 units of distance the load is moved, the effort required is moved 1 unit of distance. Therefore the effort is 4 times shorter than the load distance.

We know that the load distance is the height of the pyramid, which is 146m. So, we can use this information to find the effort distance.

Effort distance = Load distance / MA

Effort distance = 146m / 4 = 36.5m

So, the ramp would need to be 36.5m long in order to provide a mechanical advantage of 4.
