SHAFTS: TORSION LOADING AND DEFORMATION

the shaft is proportional to the applied torque and to the shaft length. L T ∝ ∝ φ φ • When subjected to torsion, every cross-section of a circular shaft remains plane and undistorted. • Cross-sections of noncircular (non-axisymmetric) shafts are distorted

Cement Kilns: Design features of rotary kilns

For this reason, from the first patents onward, the kiln hood was mounted on wheels or rollers so that it could be rolled back from the kiln nose. The need to do this later became a reason for restricting the size and cross-section of kiln hoods.

Cement Kilns: Early kilns

The lower shaft was provided with numerous poke-holes around the hearth and above the top of the burning zone. The constriction of the kiln in the top of the lower shaft maximized the draught at that point. An expansion of the cross-sectional area from the

Bars under Torsional Loading: A Generalized Beam …

In analogy with the bending moments, a new stress resultant is defined, called warping moment (or bimoment) and given by The need for the definition of this new stress resultant stems from the fact that, whereas, there still exist normal stresses acting on the cross section; hence if a new quantity is not considered, the elastic energy due to stresses will be ignored.
