The following steel beam and loading is shown. Assume the steel has a yield strength of 32ksi and a modulus of elasticity of 30,000ksi. 40 kips 2" w = 2 kip/fi- X 2" 12" 10' - 0" 2'-0' Beam cross-section a) Determine the maximum shear and moment on the beam span for the given loading b) Determine the: i) maximum tensile stress on the beam due to combined bending and axial load ii) maximum compressive stress on the beam due to combined bending and axial load iii) the tensile or compressive stress at the neutral axis due to combined bending and axial load\f1. Shear Force Diagram (SFD): . At point A: V = RA . Between A and the point load: V - RA - w . . At point load (12 ft from A): V - RA - w . 12 - P Between point load and B: V = RA - w . x - P 2. Maximum Shear Force: Vmax = Maximum value of shear force along the span 3. Bending Moment Diagram (BMD): . At point A: M = 0 Between A and point load: M - RA . x - 2 . At point load (12 ft from A): M - RA . 12 W.122 2 . Between point load and B: M - RA . x - 2 P . (x - 12) 4. Maximum Bending Moment: Mmax - Maximum value of bending moment along the span Let's draw the Shear Force Diagram (SFD) and Bending Moment Diagram (BMD) based on the reactions calculated above.RA+RB = W . L+P Let L = 20 ft. RA+ RB = 2 . 20 + 40 - 80 kips Taking moments about A: RB . 20 - 40 . 12 + 2 . 20 2 RB . 20 = 480 + 400 RB = 880 20 - 44 kips RA = 80 - 44 - 36 kips Shear Force Calculation at Key Points: . At point A: V = 36 kips . Just left of point load: V = 36 - 2 . 12 - 12 kips . Just right of point load: V = 12 - 40 - -28 kips . At point B: V - -28 + 2 . 8 - -28 + 16 - -12 kipsBending Moment Calculation at Key Points: At point A: M = 0 At point load (12 ft from A): M - 36 . 12 - 2.12- 2 - 432 - 144 = 288 kip-ft . At point B: M = 0Diagrams: Let's draw the diagrams using these calculations. I'll create the plots next.
