Determine the masses mA and mB of A and B required to hold the desk lamp of

Question:

Determine the masses mA and mB of A and B required to hold the desk lamp of mass M in balance for any angles θ and ϕ. Neglect the weight of the mechanism and the size of the lamp.

Given:

M = 400 gm

a = 75 mm

b = 75 mm

c = 75 mm

d = 300 mm

e = 300 mm

g = 9.81m/s2
