4. (a) (b) State two (2) conditions under which a body remains in equilibrium under the action of parallel forces. With the aid of a diagram, state the following: Stable equilibrium (i) (ii) Unstable equilibrium (iii) Neutral equilibrium (c) A uniform metal beam AB weighing 250N is supported at its ends. The beam carries a weight of 1600N at a distance of 1m from end A. If the beam is 8m long, determine the thrust on the support A and B.
