Which of the following would increase the mechanical advantage of an inclined plane please?

- Decreasing the angle of incline

- Increasing the length of the inclined plane
- Increasing the height of the inclined plane
- Decreasing friction between the object and the inclined plane

The possible are

Increasing the incline of the plane
You cannot increase mechanical advantage
Decreasing the length of the plane
Increasing the length of the plane

Yes, increasing the incline of the plane and increasing the length of the plane would both increase the mechanical advantage of an inclined plane. Decreasing the length of the plane would reduce the mechanical advantage. The phrase "You cannot increase mechanical advantage" is incorrect, as there are ways to increase the mechanical advantage of an inclined plane as mentioned previously.
