Lewis form factor for $$14{\frac{1}{2}^ \circ }$$ composite and full depth involute system is (where T = Number of teeth)

The speed of the sprocket reduces as the chain pitch __________ for a given number of teeth.

A shaft is subjected to a maximum bending stress of 80 N/mm2 and maximum shearing stress equal to 30 N/mm2 at a particular section. If the yield point in tension of the material is 280 N/mm2 and the maximum shear stress theory of failure is used, then the factor of safety obtained will be
