Question
Which machines has more mechanical advantage pulley or incline plane?
I asked this question before but did not quite understand the answers that were given to me. I think that the incline plane has more mechanical advantage in a friction less environment.

The MA of a pulley is 2.
The MA of an inclined plane is slope length divided by height, or 1/sinTheta
so at these angles...
angle MA
45 1/.7=1.4
60 1/.866=115
30 1/.5=2
15 1/.259=3.9
So it depends on the angle of the incline plane.
