# A Level Mechanics/Statics Question watch

1. Here we go :

Two uniform rods AB and CD, each of length 6a and mass m are freely hinged together at H where AH = CH = 2a. The rods rest in equilibrium with A and C on a rough horizontal table and at a distance 2a apart. Particles of mass 5m and 4m are suspended from B and D respectively. The coefficient of friction between each rod and the table is μ.

Find the least possible value of μ.
2. Anyone
3. Will do it tonight during prep time

Solved it already though thanks mate. Never realised 'till now the coefficient of friction can exceed 1!

Don't think it can........probably because you looked at the total friction at the to contact points
