Belt Theory - Bestorq

For a flat belt drive, the friction between the belt and pulley for a small segment of belt is =µ×????, while for a V-belt/sheave with a 38° angle, the friction would be =2.92 ×µ×???? o The same hub load and stress in the tensile members gives V-belts nearly 3x the friction of flat belts.
