Draw the influence lines for the shear and bending moment at point D .

Question

Prob. 4.3-13. The solid circular shaft in Fig. P4.3-13 is sub- jected to a distributed external torque that varies linearly from intensity of to per unit of length at x = 0 to zero at x = L. The shaft has a diameter d and shear modulus G and is fixed to a rigid wall at x = 0. (a) Determine an expression for the maximum (cross-sectional) shear stress in the shaft as a function of the distance x from the left end. (b) Deter- mine an expression for the total angle twist, d. at the free end. The shear modulus of elasticity is G. C to -t(x) P4.3-13 OB
