Problem 4.3-6 The beam ABC shown in the figure is simply supported at A and B and has an overhang from B to C. The loads consist of a horizontal force P₁ = 4.0 kN acting at the end of a vertical arm and a vertical force P₂ = 8.0 kN acting at the end of the overhang. (a) Determine the shear force V and bending moment M at a cross section located 3.0 m from the left- hand support. (Note: Disregard the widths of the beam and vertical arm and use centerline dimen- sions when making calculations.) (b) Find the value of load P2 that results in V = 0 at a cross section located 2.0 m from the left-hand support. (c) If P₂ = 8 kN, find the value of load P, that results in M = 0 at a cross section located 2.0 m from the left-hand support. P₁ = 4.0 kN 1.0 m P₂ = 8.0 kN 000 4.0 m. 1.0 m-
