Q1) The beam carries an unfactored uniformly distributed dead load (including self-weight) of G = 4 kN/m and an unfactored uniformly distributed live load of Q = 0 kN/m. Two concentrated unfactored live loads of P = 4 kN are applied at the positions shown in the figure. (Note: The load factor for G is 1.2, and for P is 1.5. There is no uniformly distributed live load.) 1.1 Find the maximum moment of the beam. Mmax 1.2 Find the neutral axis distance from the top surface. If the section is governed by the linear elastic regime, the transformed area method dn = 2 y A/ Σ A, is valid. d₁ = 1.3 Find the cracking moment. Mc = 1.4 Does this section crack? kNm (1 mark) (No answer given) (1 mark) mm (1 mark) kNm (2 mark)
