Problem 2. Solve Problem 1 using Multiframe software. Ignore the self-weight of the beam.

Submit a snapshot of your Multiframe model and answers including the shear and moment

diagrams.

If required, assume:

E 29,000 ksi (kips/in.²)

I-3,010 in.¹ (W14x233)

E-29,000 ksi (kips/in.2)

I=4,330 in. (W18X211)
