Question
A simply supported beam AB has a length of 3 m and carries distributed load which
varies in linear manner from (1.5w) N/m at A support to (3w) N/m at the B support, in
addition, a concentrated load (1w) N at 2 m from A support. The beam has hollow
circular cross section of diameter ratio 1/3 (inside diameter/outside diameter).
Determine the value of (w) if the maximum bending stress 110 N/mm², and the average
shear stress at 1 m from point A is equal to 15 N/mm?.
