Question 3
Three unbalance masses are as shown below, where m₁ = 150 g, m3 = 200 g, r₁ = 10 cm,
72 = 10 cm, 73 = 12 cm, l₁ = -20 cm, l₂ = 35 cm, l3 = 105 cm, l = 90 cm, 8₁ = -40°,
03 = 115°, and w = 20 rad/s.
1. Find mass m₂ and its angle 9₂ so that the magintude of the reaction in B is FB =
1.38 N and its angle is 0g = -78.4°.
