I was doing an A level question set by my teacher and have clue where to begin I tried drawing a diagram but still don't know how to answer the question here it is:An equilateral triangle ABC has sides of length 1 m. Forces of 3 N, 5 N and 2 N
act along AC, BD and AD, respectively, where D is the midpoint of BC. Find the
force at B and the couple, which together are equivalent to this system of forces.
