The example of rolling pair is According to Indian standards, a bolt thread of 6 mm size of coarse pitch and with allowance on the threads and normal tolerance grade is designated as The maximum efficiency of a screw jack is The given figure shows the Mohr's circle of stress for two unequal and like principal stresses (σ x and σ y ) acting at a body across two mutually perpendicular planes. The normal stress on an oblique section making an angle θ with the minor principle plane is given by For a bevel gear having the pitch angle $$\theta $$, the ratio of formative number of teeth (TE) to actual number of teeth (T) is
