Increase the advantage.
It is 15/3 = 5
18 feet
The length of the downward sloping side of the ramp would be 18 feet approximately this is pythagarus theorem of the sum of squares. the answer should in fact be the number corresponding to the square root of (10*10+15*15).
It should be like 25 feet long and put at a like 45 degrees angle
sin-1(1/20) = 3 degrees.
No, the ideal is without friction.

The mechanical Advantage is FORCE TIMES DISTANCE
Since the heights are the same, then the longer ramp.
the formula for the mechanical advantage of an inclined plane is the length divide by the height.
Length/ Hieght
Its the reciprocal of the sine of the ramp angle. > 1 / ( sin ( ramp angle ) )
The height of the Great Pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
The height of the Great Pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
The height of the great pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
The Mechanical advantage becomes smaller decreasing the amount of work that needs to be done. It will take less effort to lift the object or load
The mechanical advantage is 8/2 = 4.
