An opening in a floor is covered by a 1 × 1.2-m sheet of plywood of mass 30 kg. The sheet is hinged at A and B and is maintained in a position slightly above the floor by a small block C. Assuming that the small block C is moved and placed under the edge DE at a point 0.15 m from the corner E, determine the vertical component of the reaction at A, B, and C. (Round the final answer to two decimal places.)
