Find the lightest S-shape for the beam shown if the working stress in bending is 120 MPa. What is the maximum bending stress in the beam selected? 40 kN/m 4 m - 2.4 m 3. For the beam shown in the figure, find the shear stress at a point 30 mm above the bottom of the beam at section C. 50 mm | 14 kN E1.5 m – 3 m 100 mm I = 19.3 × 106 mmª B C A NA 62.5 mm 50 mm 2 m 100 mm 4. The simply supported wood beam, fabricated by gluing together four wooden boards, carries the three concentrated forces. The working bending and shear stresses for the wood are 1000 psi and 600 psi, respectively. Determine the largest allowable value of the force P. P 0.5 in. → -8 in.→+ 0.5 in.
