Explanation / Answer

Given,

F1 = 117 N ; F2 = 74 N ; theta-2 = 75 deg ; theta-1 = 60 Deg

a)The single force will be such that

F = F1 + F2

F = 117 cos60 i + 117 sin60 j - 74 cos75 i + 74 sin75 j

F = 58.5 i + 101.32 j - 19.15 i + 71.48 j

F = 39.35 i + 172.8 j

F = sqrt (39.35^2 + 172.8^2) = 177.22 N

Hence, F = 177.22 N

theta = tan^-1(172.8/39.35) = 77.17 deg

Hence, theta = 77.17 deg

b)The required force will be:

F3 = -F = -39.35 - 172.8 N

F3 = 177.22 N (only magnitude)

theta = 77.17

theta3 = 77.17 + 180 = 257.17 deg

Hence, theta3 = 257.17 deg
