Q. If bending moment on point B in horizontal plate is M and in vertical plane is m, then the net bending moment at point B is?

"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) m
  • (B) m
  • (C) m+m
  • (D) √m²+m²
