cad (REVISED COURSE) (3 Hours) [Total Marks : 10 Question No. 1 is compulsory. Attempt any four questions out of remaining six questions. Assumption made should be clearly stated. Assume any sultable data wherever required but justify the same. Figures to the right indicate full marks. A beam is simply supported and carries a uniformly distributed load of 40 kKN/m run over 10 the whole span. The section of the beam is rectangular having depth as 500 mm. If the maximum stress in the material of the beam is 120 N/mm? and moment of inertia of the section Is 7 x 10° mm‘, jind the span of the beam. State the assumptions made in theory of pure bending and derive the relation. 5 o _M_E y I R Prove that shear stress distribution for rectangular section 5 qmax = a4 mean se A cantilever of length 2-0 m carries a uniformly distributed load of 1 KN/m run over a length of 1-5 m from the free end, Draw the shear force and bending momént diagrams for the cantilever. : 4KN|m Cc 8 tI Zoom Two circular beams whee one is solid of diameter D and other is a hollow of outer diameter D, and inner diameter D,, are of same length, same material and of same weight. Find the ratio of section modulus of these circular beams. A cast iron beam is of T section as shown in figure. The beam is simply supported on a span of 8 m. The beam carries a uniformly distributed load of 1-5 kKN/m Jength on the entire span. Determine the maximum tensile and maximum compressive stresses. 4s ———100 mm ————} (AN ose 20MM mM T wy r A ornm Gt FEMM 4 ~~
