(i) Sketch the cross section and calculate the second moment of area (Ixx) for the compound section. (ii) Calculate the maximum uniformly distributed load (UDL) the beam can carry if the flange plates extend over the whole 7 m span. (iii) Calculate the minimum central length over which the additional flange plates are required.

Solve for letter D. thanks!

Answer the following & show your complete solutions. State whether the force on the member is in (T) tension or ( C ) compression. E 1.5 k Determine (approximately) the force in each member of the truss. Assume the diagonals can support both tensile and compressive forces. 15 ft F 2k 15 ft 2k C 15 ft 15 ft Find the axial force in member GD, BG & BC H. 3 m D 4 m 4 m 4 m 4m 3 kN 3 kN 4 kN

Determine the force in member BC, BG and FG of the truss shown by the method of sections. Indicate if the member is in tension or compression.
