WebThe theory of the torsion of thin-walled closed section beams is known as the Bredt-Batho theory and Eq. (11.20) is often referred to as the Bredt-Batho formula. It follows from Eq. (11.20) that WebA uniform, thin-walled, cantilever beam of closed rectangular cross section has the dimensions shown in Fig. The shear modulus G of the top and bottom covers of the beam is 18000N/mm 2, while that of the vertical webs is 26000N/mm 2.The beam is subjected to a uniformly distributed torque of 20Nm/mm along its length. Calculate the maximum shear …
