Biw torsional stiffness
WebTorsional stiffness is defined as the amount of torque required for twisting an object by unit radian. It is also known as the ratio of applied torque to the angle of twist (θ). It indicates how much the object is stiffer to withstand a torsional load. It is denoted by the symbol ‘K’ and can be evaluated as, Torsional stiffness, K = T θ ...
