bearing p A P f = Bending Stress A normal stress caused by bending; can be compressive or tensileTwo cases of bearing stress are presented here as an illustration. The first case represents the transfer of a compressive force between two bodies, while the second case represents the bearing stress that occurs between a bolt and a plate. This is called the bearing stress: () Therefore, bearing stress in the bracket against the pin is σ b = P/td, where t and d repre-sent the thickness of bracket and diameter of the Two cases of bearing stress are presented here as an illustration. The compressive force P is assumed to be uniformly distributed over an area (h/2)L The bearing stress is, therefore, Key m Shaft (b) Load on shaft key (h/2)L 2M rhL where M = the moment transmitted by the key the height of the key The required cross-sectional area will be computed on the basis of (the absolute value of) the largest-magnitude internal force. To facilitate the calculation, the conversionMPa =N/mm2 is used; therefore,MPa =N/mm2, and we have. (Discussed in Note Set on Torsion.) Bolts in Shear and Bearing Bearing Stress in Shaft Key Bearing stress occurs between the key and the gear and between the key and the shaft. (Discussed in Note Set on Beam Bending.) Torsional Stress A shear stress caused by torsion (moment around the axis). CaseBearing between a column and a pedestal Figure shows a column transmitting a force to a pedestal Bearing Stress A compressive normal stress acting between two bodies.
