A weight of 1200N is dropped vertically at the middle of a beam 50mmx250mm and 6m long simply supported at both ends. At what height must the weight be dropped so as to cause a stress of 14MPa in the beam? E = 8200MPa. See figure 09.
Calculate the end bearing length (in.) required for a 10-in.-by-16-in. timber beam (dressed) that is supported on a reinforced concrete wall as shown. The beam reaction is 18,000 lb and the allowable compressive stress perpendicular to the grain for the timer member is 400 psi. (Unit: in.)
A simply supported reinforced concrete beam carries a uniformly distributed load of 12 kN/m on a span of 4 m. The beam has a rectangular cross section 250 mm wide by 450 mm deep, with three 20 mm diameter steel bars placed 60 mm from the bottom of the beam, as shown below. The moduli of elasticity for the concrete and steel are 15 GPa and 200 GPa, respectively. Determine the average tensile stress in the steel and the maximum compressive stress in the concrete at the section of maximum bending moment. 450 mm 250 mm 60 mm
