Question
A built-in cantilever beam with a hollow rectangular cross-section is subjected to a uniformly distributed load as shown in Figure Q1 below. Which of the following statements best describes the shear force variation along the length, in the x direction, using the sign conventions provided in lectures? Figure Q1 For the same beam and loading case in Figure Q1, where within the cross-section will there always be zero shear stress WHEN CONSIDERING A SQUARE ELEMENT IN THE XY ORIENTĂTION (Le. the shear stress acts vertically or horizontaliy)? Oa One third of the height, measured from the bottom surface. OB.At the top and bottom free surfaces. Ocihn the centre of the cross-section. Od None of the provided answers are corect. Oe Where the effective width of the cross-section changes dramatically. OL R is not possible to say, without further information as the combined effects of bending and shear need to be accounted for.
