Select the lightest C6 channel shape to be used as a 12 ft long tension member to resist the following service loads, PD = 20 k and PL = 32 k.The member will be connected by a transverse weld at the end of the channel only. Use A36 Grade 36 steel with Fu = 58 ksi.
The plate shown is attached by using three M12x2 grade 8.8 bolts. Which screw is subjected to the largest stress? What safe load ( static) F can be supported by the screw for n=1.5.
Select an ST shape to be used as a 20 ft long tension member that will safely support the service tensile loads:PD = 35 k,PL = 115 k, and PS = 65 k (snow). The connection is through the flange with two lines of three 3/4-in Ø bolts 4 in on center.Use A572 Grade 50 steel. Neglect block shear.
