Given a = 1.5 m, b = 0.25 m, c = 0.25 m, d = 10 N/m, e = 2 N/m, find the equivalent resultant force and couple moment acting at point O. Assume upwards forces and counterclockwise moments are positive. d FR = (MR)O = a N Nm e b C Given a = F3 0.5 m, b = 0.6 m, c = 0.8 m, 0 = 45 F = 300 N, F = 100 N, M1 = 180 Nm, = 100 Nm, and M2 = 200 N (which lies in the x-z plane), M1 F1 A B C F3 0 y C a M2 F2 determine the equivalent force and couple moment acting at point O. FR = { i+ j+ k} N MRO = |i+| j+ k} Nm
