(a) Figure Q2(b) shows two steel bars each of 2.0 m length and 30 mm in diameter supporting a temporary road sign weighting 5000 kg. Take: E = 205 kN/mm², Poisson's ratio v = 0.3 and g = 9.81 m/s2 [6 marks] [5 marks] () Calculate the shortening per bar. (ii) Calculate the change in lateral dimension per bar. (iii) Calculate the change in volume per bar. (iv) Calculate the volumetric strain per bar. [5 marks] [2 marks] Road Sign M= 5000 kg Figure Q2b 2m (Figure not to scale)
