Parameter Steel .

Modulus of Elasticity 30,000,000 psi

Proportional/Elastic Limit 34,000 psi

Allowable Bending Stress 24,000 psi

Allowable Axial (C or T) Stress 24,000 psi

Allowable Shear Stress 16,500 ps

You have a 25-foot long, simply supported W12-50 steel beam. Itis supporting a single 10,000# point load at its midpoint.Including the weight of the beam, answer the questions below:

A. What is the maximum bending moment (foot-#) and resultingmaximum bending stress (psi)? Is this allowable?

B. What is the maximum vertical shear (#) and resulting averageshear stress (psi)? Is this allowable?

C. What is the maximum deflection (inches)? Is this permissibleif the allowable deflection is (1:360)?
