Homogeneous rectangular plate weighing P = 5kN with sides AB = 3L; BC = 2L; it is 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 kNm, 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: F₁ = 4kN; α₁ = 0 °; H: F₃ = 8kN; α₃ = 60 °.
