Inclined plane examples

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

a ladder

a circular staircase

a knife

a parking ramp

an axe

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

Unknown said...: Ladder-Inclined Plane
A circular staircase-inclined plane
A Knife-Wedge
A parking Ramp-inclined Plane
An axe- Wedge

I think the Parking lot would have the lowest AMA; October 31, 2008 at 9:53 AM
Unknown said...: lever
screw
wedge
inclined plane
lever
the axe because its a 3rd class lever; October 31, 2008 at 9:53 AM

Jennie said...: a ladder--inclined plane

a circular staircase--inclinded plane

a knife--wedge

a parking ramp--inclined plane

an axe--wedge
LOWEST AMA--parking ramp..i had no idea...; October 31, 2008 at 9:54 AM

I don't know.; October 31, 2008 at 9:54 AM
Unknown said...: no clue; October 31, 2008 at 9:55 AM
Unknown said...: 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; October 31, 2008 at 9:55 AM

Unknown said...: 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; October 31, 2008 at 9:59 AM
