Use the engineers’ theory of bending to calculate the maximum bending stress in the asymmetric hollow section to a bending moment of 1750 N m about a horizontal axis through the centre of area.
b. Using the principle of parallel axes, answer the questions below to perform a manual calculation to show that the second moment of area about the horizontal axis through the centre of area for the asymmetric hollow section is 194 x 103 mm4 (to 3 sig. fig.). Show all your workings. i. Show that the […]
