Quiz 3
Problem: the simple beam AB shown in the figure supports a concentrated load and a segment of uniform load.
(a)
Draw the shear-force and bending-moment diagrams for this beam.


(b)
Calculate the maximum shear stressmaxand the maximum bending stress maxin this beam if the cross section is rectangular with width 150mm and height 200mm. (neglect the weight of the beam).
