The solid circular rod has a cross-sectional area of 440 mm. It is subjected to a uniform axial distributed loading along its length of w= 10 kN/m. Two concentrated loads also act on the rod: P = 3 kN and Q = 4 kN. Determine the normal stress in the rod at x = 1.5 m. Assume a 0.7 m and b = 1.3 m. a B W Answer: = i MPa
