ANALYSIS OF TORSIONAL RIGIDITY OF CIRCULAR BEAMS WITH DIFFERENTudENGINEERING MATERIALS SUBJECTED TO ST. VENANT TORSION

摘要

Many engineering structures, such as airplane wings, beams and shafts are subjected to higher torsional forcesudtoday due to advancement in Structural Engineering, in terms of size and technology. In this paper, we analyzed theudresistance of circular beams, of different engineering materials, to their corresponding twisting moments. We obtained theudtorsional rigidity for the different beams as the ratio of twisting moment to the angle of twist per unit length. It is observedudthat torsional rigidity of the beams is a function of their areas and the engineering material they are made up of.udSpecifically it is observed that the circular beam made up of brass engineering material has the greatest torsional rigidityudamong the twelve engineering materials considered.
