Problem 1: Determine the internal forces at point J for the structure shown, where member BD can only carry axial forces. Take the dimension a = 160mm and the external load P = 450N
Problem 2: Given the beam shown below, determine the shear force and bending moment at point C. Given the dimensions a = 3 m, b = 6.8 m and c = 2m, and the load intensities e = 9.5 kN/m and f = 2.5 kN/m.
