City Guilds Model Questions Vol1 2023 Engineering Question 4
Practice objective / multiple choice question 4 from the 2023 City Guilds Model Questions Vol1 Engineering examination.
A simply supported rectangular steel beam spans \(6\) m and carries a uniformly distributed load of \(20\) kN·m\(^{-1}\). The beam width is \(150\) mm and the height \(h\) mm is to be chosen. The allowable bending stress for the steel is \(150\) MPa. Using the bending formula \(\sigma = \dfrac{M y}{I}\) with \(I=\dfrac{b h^{3}}{12}\) and \(y=\dfrac{h}{2}\), determine the minimum integer height \(h\) (in mm) that satisfies the stress limit.
