The question is:- Four given pulls and thrusts act on a ring. Find their equilibrant. The pulls and thrusts are as follows:
N = 58 - thrust
M = 105 - pull
L = 40 - thrust
K = 72 - pull
Angles are as follows:
NM - 73 deg
NL - 149 deg
NK - 194 deg

The methodology I have used is calculate the equilibrium for the pulls and thrusts separately. Then subtract the thrusts from the pulls. The answer I get is 60.36, however the answer given is 88.5. Where have I gone wrong?
