Question 4 [6] A beam with effective length 6 is clamped at both ends and bends due to a uniformly distributed load q which includes its own weight. The magnitudes of the forces at the clamps are denoted by P (at the left) and Q (at the right). The magnitudes of the couples due to the clamps are K (at the left) and L (at the right). Determine the deection at the middle of the beam in terms of the known values E, I, E and
