Using Microsoft Excel, prepare a design calculation routine that includes:

A$.$ All input cells a medium gray fill. Provide input values for a tensile force and for

ACI standard rebar size. The rebar size should allow the user to select from any

ACI standard rebar size.

B$.$ Provide an output for the area of the rebar size selected.

C$.$ Provide a calculation to compute the tensile capacity of the rebar size selected.

D$.$ Provide a check that evaluates whether the selected rebar size is sufficient or

insufficient to resist the input tensile force.

E$.$ Cite all sources and any assumptions made.
