Suspension bridge diagram

Guided pulley support and roller support


For guided pulley support,

T(sinθ+sinα)

T(cosθ−cosα)

BM=Horizontal force∗Height of the tower


For roller support,

T1=T[cosθ/cosα]

T1sinα+Tsinθ

Since, saddle is having frictionless rollers, there is no horizontal force and hence no bending moment on tower.

$T_1sin\alpha + Tsin\theta$ [vertical]
