GATE ME 2003

MCQ (Single Correct Answer)

-0.3

The beams, one having square cross section and another circular cross-section,are subjected to the same amount of bending moment. If the cross sectional area as well as the material of both the beams are the same then

Maximum bending stress developed in both the beams is the same

The circular beam experiences more bending stress that the square one

The square beam experiences more bending stress than the circular one

As the material is same both the beams will experience same deformation
