(a) The lightest W10 section using Load And Resistance Factor Design (LRFD) method.

Question

In the loaded truss shown, AB=BC=CD=DE=3.4 m, BF=CG=GI=DH=HJ=(EK)/2=5.1 m. If the loading P=3.3 kN, calculate the force (in kN with proper sign) in member HK (correct to 1 decimal place). (sign convention: tensile force in a member is taken with positive sign)

The rigid bar BC is supported by the steel rod AC of cross-sectional area 0.3 in2. Find the elongation (in inches) of rod AC caused by the 3088-lb load if x = 10 ft and θ = 56ᵒ. Use E = 29227 ksi for steel. Note: Round off the final answer to four decimal places.

The rigid bar BC is supported by the steel rod AC of cross-sectional area 0.35 in2. Find the vertical displacement (in inches and absolute value) of point Ccaused by the 2684-lb load if x = 9.9 ft and θ = 49.3ᵒ. Use E = 29213 ksi for steel. Note: Round off the final answer to four decimal places.
