4) The mechanical advantage in a class 3 lever is always less than 1 because the load arm is longer than the effort arm
5) The mechanical advantage in a class 2 lever is always over 1 because the effort arm is longer than the load arm Inclined Planes:
1) Ramp
2) Make the distance of the ramp longer
3) An inclined plane is a sloping ramp in a upward angle which heavy loads can be pulled by ropes or chains and can be pushed by yourself up to where you want it to go
