Q. Calculate the tension in the rope of pulley C.

"The layout of a shaft supported on bearings at A & B is shown. Power is supplied by means of a vertical belt on pulley B which is then transmitted to pulley C carrying a horizontal belt. The angle of wrap is 180’ and coefficient of friction is 0.3. Maximum permissible tension in the rope is 3kN. The radius of pulley at B & C is 300mm and 150mm"

(A) 6778.3n and 7765.3n

(B) 5948.15n and 2288.75n

(D) none of the listed

Correct : Option (B)

Explanation:

 (p₃-p₄)x150=549.3×1000 and p₃/p₄=2.6. hence p₃=5948.15n and p₄=2288.75n.
