Fig.2. 6
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 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: H: F₂ = 6kN; α₂ = 30 °; D: F₄ = 10kN; α₄ = 90 °.
