Simple Machines

 

1. Mechanical Advantage (MA) =?

A            B          C

 

 

 

 

 

 

 

A = 2

B = 4

C  = 1

 

 

2. What is the mechanical advantage of the inclined plane?

3. How much effort force would be needed to push the dump truck up the mountain?

 

 

 

 

 

 

 

 

2.   MA = 3

3.   Applied Force = 500N

 

 

 

 

 

 

 

 

4. How much effort force is required to lift the 150kg load if the distance from the fulcrum to load is 2 m and the distance from the fulcrum to the effort is 10 m?

Lever is a simple machine

 

 

 

 

 

 

 

 

 

4. MA = 10m/2m = 5

Load / 5 = 1,500N/5 = 300N
