Question Description
Attempt All Questions sub parts from each question.Sagging of a bridge A bridge is designed such that it can withstand the load of the flowing traffic, the force of winds and its own weight. Let us consider the case of a beam loaded at the centre and supported near its ends as shown in Figure. A beam of length l, breadth b, and depth d when loaded at the centre by a load W sags by an amount given byFrom the equation, we see that to reduce the bending for a given load, one should use a material with a large Young’s modulus Y. For a given material, increasing the depth d rather than the breadth b is more effective in reducing the bending, since δ is proportional to d–3 and to b–1 (of course the length l of the span should be as small as possible).Amongst bridge materials steel has the highest and most favorable strength qualities, and it is therefore suitable for the most daring bridges with the longest spans. Normal building steel has compressive and tensile strengths of 370 N/sq mm, about ten times the compressive strength of a medium concrete and a hundred times its tensile strength. A special merit of steel is its ductility due to which it deforms considerably before it breaks, because it begins to yield above a certain stress level.Q. Why ductility is the special merit of steel?a)Ductility allows structures to bend and deform to some extent without rupturing.b)Ductility offers the structure a high rigidityc)Ductility prevents the structure to sag while overloadedd)Ductility offers less corrosionCorrect answer is option 'A'. Can you explain this answer? for Class 11 2024 is part of Class 11 preparation. The Question and answers have been prepared according to the Class 11 exam syllabus.
