The beam is laterally unsupported throughout the span.
Understand the Problem
The question is asking about various engineering design and analysis tasks, including failure modes of beams, structural designs for cranes, determination of load conditions for trusses, and welding provisions. These involve both explaining concepts and performing engineering calculations.
Answer
a) Failure modes: bending, shear, lateral-torsional buckling. b) Design an I-section based on loads and span.
The final answer is: a) Failure modes include bending failure, shear failure, lateral-torsional buckling, and local buckling, applicable sketches should show these forms. b) Design involves calculating maximum bending moment, selecting appropriate I-section dimensions considering deflection and strength, and checking for lateral stability.

More Information
Common beam failure modes include bending, shear, and buckling due to excessive loads or inadequate design. The I-section is effective for carrying bending loads due to its high moment of inertia.
Tips
Ensure to consider all possible failure modes and accurately compute the maximum bending moments and shear forces.
