Find the angle between the forces shown if they are in equilibrium
A B C
1)Use the cosine rule to find the angles in the triangle Cos C = C = A B C Cos B = B = A = 31.8
2) Interpret the angles back onto the force diagram C = B = A = – = 67.2
2) Interpret the angles back onto the force diagram C = B = A =
2) Interpret the angles back onto the force diagram C = B = A = – 31.8 = 148.2
2) Interpret the angles back onto the force diagram – 31.8 = 148.2
2) Interpret the angles back onto the force diagram –67.2 – = 144.6
