HW10.9. Draw stress elements for a cantilever beam The cantilever beam of length 3L is subject to concentrated loads P and 2P and has the thin-walled cross- section illustrated below. The cross-section has uniform thickness t and moment of inertia with respect to the centroidal z-axis given by I= 3140 t. Use t 6 mm. L=118 mm and P = 10 kN. == 2L L 2P Z NAG 5t 10t 10 t 10 t 1) Determine the numerical value of the shear force and bending moment at a cross-section located at x=59 mm. Remember to use the sign conventions for shear forces and bending moments. V(x) = 10 kN M(x)=590 N.m 2) For the cross-section located at x=59 mm, determine the state of plane stress at point H (i.e., y = 5 t) in the r - y coordinate system. MPa MPa MPa Tay D
