The rotating cage apparatus is used in the oil industry as a simple and effective test for corrosion. The apparatus generates a large amount of flow induced corrosion and is used by researchers to design effective corrosion inhibitors. While the apparatus is used frequently, the fluid mechanics of the problem is not well understood. Importantly, there is no correct model for the shear stress pr...

the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...

ZI E M E R, R. R. 1978. An apparatus to measure the crosscut shearing strength of roots. Can. J. For. Res. 8: 142-144. Loss of tree root strength after timber cutting is a principal mechanism leading to slope failure and landslides. Measurement of root shear strength changes can be useful in evaluating effects of logging on slope stability. The simple apparatus described measures shear strength...

In order to reduce the power consumption of screw conveyor and improve productivity, this study investigated such mechanical characteristics rubbed maize straw as coefficient sliding friction, angle repose, internal friction coefficient, cohesion, flow function value compressible with respect its moisture content density. An experiment was designed consists a characteristic test-bed, direct she...
