A beam will support a combination of dead, live, and earthquake loads. The Load Duration Factor for Dead is 0.9, Live is 1.0, and Earthquake is 1.6. The Dead load causes a stress of 300 psi, the live load causes a stress of 200 psi, and the earthquake causes a stress of 100 psi. The tabulated strength of the wood is 1000 psi. What is the critical (largest) Demand/Capacity ratio for the beam? (Demand/Capacity is fb/Fb'.)
