A timber [E = 12 GPa] beam is loaded and supported as shown The cross section of the timber beam is 100 mm wide and 300 mm deep. The beam is supported at B by a 12-mm-diameter steel [E = 200 GPa] rod, which has no load be- fore the distributed load is applied to the beam. After a distributed load of 7 kN/m is applied to the beam, determine (a) the force carried by the steel rod. (b) the maximum bending stress in the timber beam. (c) the deflection of the beam at B. 300 mm (1) 100 mm 5 m 7 kN/m В 4 m 2 m Partial Answer: Max bending stress is 7.75 Mpa.
