Learning Goal: To use the superposition principle to find the state of stress on a beam under multiple loadings. The beam shown below is subjected to a horizontal force P via the rope wound around the pulley. The state of stress at point A is to be determined. 1d₂ d₁ da d₂ 100 mm 15 mm- 20 mm 150 mm - 1 The dimensions are d₁ = 2.25 m, d2 = 0.65 m d3 = 0.95 m. d4 = 325 mm, and r = 190 mm. The applied force has magnitude P = 6 kN. 20 mm 200 mm Part A - Support Reactions and Internal Loading Determine the support reactions Cy and C and the internal normal force, shear force, and moment on the cross-section containing point A.
