You have started your first job at the prestigious architecture and structural
engineering firm of

assignment which is expected to take you
a few days. However, they will be observing
quality of your work on this assignment in order to assess your value and determine your future
assignments. You ar

To impress your superiors, perform

b. Factor of Safety for the structure must be 2.0 with respect to yielding in tension or
compression and 2.5 with respect to yielding in shear.
Perform a complete prismatic beam design as described in the ENGR300 course by performing
the following steps.
Draw clear and accurate shear and moment diagrams of the beam with maxi
labeled and non
linear curves identified
Tentatively select a W
beam based on maximum normal stress.
Check the tentatively selected beams for maximum shear
locations on the beam where the shear and moment could possibly
exceed the allowable stresses.

Produce a report which makes a clear and concise case for the beam

way of demonstrating this is to show the next lightest beam would exceed the allowable

Report the actual factor of safety as the yield stress
the actual maximum stress in both compression and shear.
