The measured extreme fibre strains at mid span of a simply supported beam, loaded with uniformly distributed load (Figure 3a), are: - 5000*10-6 at A and + 5000*10-6 at B. Determine: (a) the bending moment on the mid-span section when the beam is made of elastic-perfectly plastic stress-strain curve as shown in Figure 4b. (b) the uniformly distributed load o when the beam section at mid span becomes fully plastic. Express your answer with the appropriate units. 100 А 600 0 Unit: mm B 2.5m 2.5m Figure 4a 300 MPa 0.0015
