Question

3. Figure shows the singly symmetrical cross-section of a thin-walled open

section beam of constant wall thickness t, which has a narrow

longitudinal slit at the corner 15. Calculate and sketch the distribution of

shear flow due to a vertical shear force S acting through the shear centre,

S and note the principal values .Also determine the position of shear

center. (10)

4. Draw the shear flow distribution for the cross-section shown in figure.
