Problem 1
Knowing that the couple shown acts in a vertical plane, determine the stress at (a) point A, (b)
point B.
Figure P1
Problem 2
Using an allowable stress of 155 MPa, determine the largest bending moment M that can be
applied to the wide-flange beam shown. Neglect the effect of fillets.
Figure P2
Problem 3
The beam shown is made of a nylon for which the allowable stress is 24 MPa in tension and 30
MPa in compression. Determine the largest couple M that can be applied to the beam.
