THE PRACTICE STUDIO
Go slowly. Ask why. Make it yours.
PRACTICE / Static equilibrium
Where should the lighter mass sit?
A 6 kg mass is 0.40 m left of the pivot on a massless horizontal beam. A 4 kg mass balances it on the right.
Find the right mass distance from the pivot.
Organize the givens & assumptions
- mleft = 6 kg
- rleft = 0.40 m
- mright = 4 kg
Massless rigid horizontal beam; point masses and frictionless pivot; static equilibrium in uniform gravity.
