Knowing that each pulley has a radius of 250 mm, determine the components of the reactions at D and E. (A 4.8 kN load hangs from the rope. Member ACE is horizontal, 4 m long, pinned to the wall at E, with C at its midpoint; member ABD is pinned to the wall at D, 1.5 m above E, with B at its midpoint; pulleys are at A and B. The rope hangs vertically from the left of pulley A, passes over A, runs parallel to ABD to pulley B, passes over B and runs vertically down to an anchor on ACE directly below the right edge of pulley B.)
