Q1 (a) Describe the FOUR (4) assumptions for constructing the collapse mechanism of a slab in Yield Line Theory. (4 mark) (b) The trapezoidal slab \( \mathrm{ABCD} \) is simply supported along the two edges, \( \mathrm{AB} \) and \( \mathrm{CD} \), and pinned along \( \mathrm{BC} \) as shown in Figure Q1(b). The slab is subjected to a uniformly distributed load of \( 15 \mathrm{kN} / \mathrm{m}^{2} \). Determine the maximum resistance moment for the failure mechanism of the slab if edge EF displaced one (1) unit. Given \( m^{\prime}=2 \mathrm{~m} \).
