Q1. An 80-m-long wire of 5-mm diameter is made of a steel with E = 200 GPa and an
ultimate tensile strength of 400 MPa. If a factor of safety of 3.2 is desired, determine (a)
the largest allowable tension in the wire, (b) th
Problem set 5
The cross section of a beam is shown below; the beam can withstand a
maximum tensile stress of 60MN/m2 and a maximum compressive stress of 45MN/m2.
If the beam is simply supported at each end what is the maximum bending mo
