 4.6. Two vertical forces are applied to a beam of the cross section shown. Determine the maximum tensile and compressive stresses in portion BC of the beam. (Hình 46)

4.7. Knowing that a beam of the cross section shown is bent about a horizontal axis and that the bending moment is 6 kN.m, determine the total force acting on the top flange. (Hình 47)

4.8. Knowing that a beam of the cross section shown is bent about a horizontal axis and that the bending moment is 50 kip.in., determine the total force acting (a)on the top flange (b)on the shaded portion of the web. (Hình 48)

4.9. The beam shown is made of a nylon for which the allowable stress is 24 MPa in tension and 30 MPa in compression. Determine the largest couple M that can be applied to the beam. (Hình 49)

4.10. Knowing that for the extruded beam shown the allowable stress is 12 ksi in tension and 16 ksi in compression, determine the largest couple M that can be applied. (Hình 410)
