Inclined Plane, Wedge, and Screw
What is an inclined plane?
A flat surface set at an angle or incline with no moving parts.
What are the properties of a screw?
Change rotary motion into linear motion Used as a threaded fastener Large MA Large amount of friction loss
How do you solve for IMA with a screw?

What does metric info show?
Diameter and pitch
What does US thread info show?
Diameter and thread per inch
How do you solve for AMA of a wedge?
Fr / Fe
How do you solve for AMA with a screw?
Fr / Fe
How do you solve for the AMA of an inclined plane?
Fr / Fe
What are the two components of a screw?
Inclined plane wrapped around a cylinder, forming the path and pitch Wheel and axle used to create rotary motion
What is a wedge?
It functions as a moving inclined plane. Tapers at a thin edge and is used for splitting, lifting heavy bodies, or for tightening by being driven into something.
How do you solve for IMA of a wedge?
L (perpendicular to height) / H
How do you solve for the IMA of an inclined plane?
L (slope) / H
How do you solve for efficiency?
[AMA / IMA] * 100
