Propose a different design for the beam to carry the loading shown in Figure that will be safe but lighter than cither design described in Problems.

Problem

An alternate design for the beam to carry the load shown in Figure is shown in Figure. The material for the hollow tube is ASTM A501 hot-formed structural steel and the plates are made from ASTM A36 structural steel. Evaluate whether or not this design is safe. Also, compute its total weight and compare it to the W-shape you specified in Problem.

Problem

For the beam loading shown in Figure, specify the lightest standard wide flange beam shape if it is to be made from ASTM A992 structural steel. The load is static. Use the AISC specifications. Compute the total weight of the beam.
