The disc shear

WebJun 29, 2001 · The disc pump is engineered with wide internal tolerances because all of the disc surfaces are involved in pumping. Obviously, this design has advantages and disadvantages. Wider clearances reduce clogging and give the pump excellent handling capability in pumping abrasive and shear-sensitive materials. WebDuring lifting, a lot of attention is devoted to the compressive and shear forces acting on the spine due to the association with tissue damage (Adams et al., 2006). While compression is defined as the force acting perpendicular to the mid-plane of the intervertebral disc, shear forces act parallel to the disc and 90º to the compressive forces.
