Activity 1.1.1 Third Class Lever

This is my third class lever!

Calculations:
Ideal Mechanical Advantage (IMA)
IMA= Distance(effort force)/Distance(resistant force)
IMA= 8 Lego holes/ 17 Lego holes
IMA= 0.47

Ideal Effort Force to overcome the known Resistance Force
MA(mechanical advantage)=Force(resistance)/Force(effort)
 0.43 = 1.5 Newtons/ Force(effort)
Force(effort)= 3.5 Newtons

Actual Mechanical Advantage (AMA)
AMA=Force(resistance)/Force(effort)
AMA= 1.5 Newtons/ 3.5 Newtons
AMA= 0.43

Efficiency of the lever system
Efficiency= AMA/IMA
Efficiency= 0.43/0.47
Efficiency= 0.91

Examples of 3rd Class Lever:

1. Fishing pole
2. Tweezers
