Classify the following machines (lever, pulley, wheel/axle, screw, wedge, inclined plane):

a ladder

a circular staircase

a knife

a parking ramp

Which type of machine(s) above has the LOWEST AMA? Why do you think this is so?

  9. ladder =inclined plane
    circular stair= screw
    Knife =wedge
    parking ramp =inclined plane
    axe = wedge

    circular stair case, cause it goes in a circle gradually rising, making it easy and long to go up that distance

  15. Ladder - Inclined Plane
    A cicular staircase - screw
    A knife - wedge
    A parking ramp - Inclined Plane
    An Axe - Wedge.


    I think the Axe would have the lowest AMA because it is a third class lever
