Activity 1.1.1 First Class Lever

This is my first class lever.

Calculate:
Ideal Mechanical Advantage (IMA)
IMA= Distance(effort force)/Distance(resistant force)
IMA= 13 Lego holes/ 13 Lego holes
IMA= 1

Ideal Effort Force to overcome the known Resistance Force
MA(mechanical advantage)=Force(resistance)/Force(effort)
1= 1.5 Newtons/ Force(effort)
Force(effort)= 1.5 Newtons

Actual Mechanical Advantage (AMA)
AMA=Force(resistance)/Force(effort)
AMA= 1.5 Newtons/ 1.5 Newtons
AMA= 1

Efficiency of the lever system
Efficiency= AMA/IMA
Efficiency= 1/1
Efficiency= 1

Examples of 1st Class Lever:

1. Seesaw- the folcrum is in the center of the effort force and resistance force
2. Elbow extension
