You are asked to construct a mobile with four equal m = 185 kg masses, and three light rods of negligible mass and equal lengths. The rods are of length 55 cm.

(a) At what location on the level 1 rod should the free end of rod 2 be attached?
L1 =   

(b) At what location on the level 2 rod should the free end of rod 3 be attached?
L2 =   

(c) At what location on the level 3 rod should the whole assembly be suspended from so that the mobile is in equilibrium?
L3 =
