OHb and bending

What is the stress that occurs at the top and bottom of a beam when it is subjected to a bending moment?

• Tensile stress, compression stress

• Shear stress, axial stress

• Bending stress, torsional stress

• Bearing stress, thermal stress

What is the neutral axis of a beam?

• The line along which there is no stress due to bending moment

• The line along which the maximum stress occurs

• The line along which the minimum stress occurs

• The line along which the shear stress is maximum

What is the relationship between the bending moment, the curvature of the beam and the moment of inertia of the beam?

• They are directly proportional

• They are inversely proportional

• They are unrelated

• They are directly proportional for some beams and inversely proportional for others

What is the shear force at the mid-span of a simply supported beam with a uniformly distributed load?

• A. Zero

• B. Half of the total load

• C. Equal to the total load

• D. Double the total load

A simply supported beam of span L is carrying a uniformly distributed load w. At what distance from the left support is the shear force equal to half of the total load on the beam?

• A. L/4

• B. L/2

• C. 3L/4

• D. None of the above
