. Oblique stress on a member PROBLEM 1.31 5.0 in 3.0 in. 7 The 1.4-kip load P is supported by two wooden members of uniform cross section that are joined by the simple glued scarf splice shown. Determine the normal and shearing stresses in the glued splice. 70 psi (normal stress), 40.4 psi (shearing stress) PROBLEM 1.33 6 mm A steel pipe of 300 mm outer diameter is fabricated from 6 mm thick plate by welding along a helix which forms an angle of 25 with a plane perpendicular to the axis of the pipe. Knowing that the maximum allowable normal and shearing stresses in directions respectively normal and tangential to the weld are o = 50 MPa and r = 30 MPa, -Well determine the magnitude P of the largest axial force that can be applied to the pipe. 337 kN PROBLEM 1.36 A centric load P is applied to the granite block shown. Knowing that the resulting maximum value of the shearing stress in the block is 18 MPa, determine (a) the magnitude of P. (b) the orientation of the surface on which the maximum shearing stress occurs, (c) the normal stress exerted on that surface, (d) the maximum value of the normal stress in the block. 140 mm 140 mm (a) 706 kN, (b) 45, (c) 18 MPa, (d) 36 MPa (compression)
