The billboard sign shown weighs 4000 lb and is supported on a 15" circular hollow steel tube with 3/8" thickness. The sign will be built in west Mobile and is subjected to wind forces with maximum wind speed of 160 mph. The hollow steel tube has a maximum compressive/tensile strength of 50 Ksi and a maximum shear strength of 10 Ksi. Determine if the hollow steel tube has enough axial and shear strength to support loads applied to the sign....
The simply-supported beam having I-beam cross-section as shown in figure is to carry a uniformly distributed load over its entire 1.2m length. Specify the maximum allowable load if the beam is made from malleable iron, ASTM A220, class 80002. The allowable tensile stress is 164 MPa and allowable compressive stress is 412 MPa. The centroid of the section is located at 35 mm from the bottom and moment of inertia are Ix = 2.66 x 10 mm". (a) Draw loading...
A simply supported composite beam 3 m long carries a uniformly distributed load of intensity q= 30 kN/m (see figure).
