#### Transcript of The Six Simple Machines Assignment

Levers: Pulleys: Wheel and Axle: Inclined Plane: Screws: The Six Simple Machines

Example:
-Effort arm is 15 cm long and the load arm is 5 cm long.
-15÷5=3
- So the MA would be 3.

MA= Diameter of Wheel
Diameter of Axle
Example:
-The diameter of the wheel was 18 cm and the diameter of the axle was 6.
-18÷6=2.
- So the MA would be 2.
MA= Total # of Strands that Support a Load.

So in a fixed pulley the mechanical advantage is on because there is only one “lifting rope”. MA= Length of Plane
Height of Plane
Example:
Let’s take the picture of the person pushing the wardrobe using a ramp. If the length of the plane was 6 metres and the height of the plane was 3 the MA would be 2. 6÷3=2 MA= Circumference
Pitch Wedges: MA = Length of Wedge
