Two wooden members of uniform rectangular cross section as joined by the simple glued scarf splice shown. knowing that the maximum allowable shearing stress in the glued splice in 620 kpa, determine (a) the largest load p that can be safely applied, (b) the corresponding tensile stress in the splice. a steel pipe of 12-in. outer diameter is fabricated from 1 / 4-in.-thick plate by welding along a helix that forms an angle of 25 degree with a plane perpendicular to the axis of the pipe. knowing that the maximum allowable normal and shearing stresses in the direction respectively normal and tangential to the weld are sigma = 12 ksi and tau = 7.2 ksi, determine the magnitude p of the largest axial force that can be applied to the pipe. a steel pipe of 12-in. outer diameter as fabricated from 1 / 4-in.-thick plate by welding along a helix that forms an angle of 25 degree with plane perpendicular to the axis of the pipe. knowing that a 66 ksi axial force p is applied to the pipe, determine the normal and shearing stresses in directions respectively normal and tangential to the weld.
