Homogeneous rectangular plate weighing P = 5kN with sides AB = 3L; BC = 2L; fixed at point A by a spherical hinge, and at point B by a cylindrical hinge (bearing) and held in balance by a weightless rod CC ´. A pair of forces with a moment M=6kNm, lying in the plane of the plate, and two forces act on the slab. Determine the reaction of bonds at points A, B and C. When calculating, take L = 0.8 m.
Given: E: F₂=6кН; α₂=90°; D: F₃=8кН; α₃=30°.
