Question

Learning Goal: To identify the directions of the shear and normal stresses in a simply supported straight beam subjected to a vertical point load. When a beam is subjected to both internal shear and bending moment, both normal and shear stresses will be developed within the beam. The normal stress at a point is related to the bending My moment by the flexure formula, o = where y is the I perpendicular distance of the point from the neutral axis. The shear stresses on a vertical section face in the yz-plane) will create complementary shear stresses along longitudinal planes (in the x z-plane). In this tutorial, the direction of the stresses on an element are investigated qualitatively. Figure < 1 of 1 A B

Answer 1

for stress element at B force Shear stress at B is negative, so shear stress be positive. Normal stress at B in x-dirn is tensile in nature Normal stress at B in Yo dirn is zero. So stress element at & will be B have doubt Please comment if you any Please upvote if the solution is helpful.
