Phi sigma B2
The stress generated by the cross section consists of three parts:
1 tensile stress generated by tensile stress
2 tensile stress produced by centrifugal force
3 bending stress produced by bending
Stress distribution of belt
Max= 1+ b1+ sigma sigma sigma sigma C
From the figure, with the maximum stress into the small pulley in belt tight side
