N= Number of Sides
7
Q
Mechanical Adv Lever Classes
A
Class 1 - Fulcrum in the middle Mech Adv = Mass ÷ Force
Class 2 - Mass in the middle Mass = Force x Mech Adv
Class 3 - Force in the middle
8
Q
Mass = ?how do you calculate
A
Mech Adv = Force Arm ÷ Mass Arm
Mass = Force x Mech Adv
Force = Mass ÷ Mech Adv
