Most shafts will transmit torque through a portion of the shaft. Typically the torque comes into the shaft at one gear and leaves the shaft at another gear. A free body dia-gram of the shaft will allow the torque at any section to be determined. The torque is often relatively constant at steady state operation. The shear stress due to the torsion
SDI has expanded its shaft development capabilities through acquisitions to include blind shaft drilling and geotechnical engineering services. Blind shaft drilling uses reverse circulation drilling to develop shafts from the surface without miners entering the shaft. This allows shafts to be developed more quickly than conventional sinking. SDI has also acquired geotechnical …
