Question

Fig. 8 shows the regular hexagonal cross-section of a thin-walled beam of sides ‘a’ and constant wall thickness t. The beam is subjected to a transverse shear force S, its line of action being along a side of the hexagon, as shown. Find the rate of twist of the beam in terms oft, a, S and the shear modulus G. Plot the shear flow distribution around the section, with values in terms of S and a
