1. Problem 1:
Knowing that for the casting shown the allowable stress is 5 ksi in tension
and 18 ksi in compression, determine the largest couple M that can be applied.

3. Problem 2:
Knowing that the bending moment in the reinforced concrete beam is 100 kip*ft and
that the modulus of elasticity is 3.625E6 psi for the concrete and 29E6 psi for
the steel, determine (a) the stress in the steel, (b) the maximum stress in the concrete.

5. Problem 3:
Knowing that the allowable stress for the beam shown is 90 MPa,
determine the allowable bending moment M when the radius r of the fillets is 8 mm

7. Problem 4:
Knowing that the clamp shown has been tightened until P = 400 N,
determine (a) the stress at point A, (b) the stress at point B, (c) the
location of the neutral axis of section a-a.
