1. You are told to design an unreinforced concrete bridge such that the likelihood of the pillars failing in compression is 1 out of 10,000. You test 100 concrete compression samples, the same size as your beam, and find that the Weibull modulus is 3.4 and the characteristic strength is 30.7 MPa. a) What diameter pillar should you design if each pillar must support 200 metric tons of load (note 1 metric ton = 1000 kg, 1 kg =9.8 N)?...
