A 12-kN tensile load will be applied to a 50-m length of steel wire with E = 200 GPa. Determine the smallest diameter wire that can be used, knowing that the normal stress must not exceed 150 MPa and that the increase in length of the wire must not

The pressure drop across a valve through which air flows is expected to be 10 kPa. If this differential were applied to the two legs of a U-tube manometer filled with mercury, estimate the manometer deflection.

Both 1042 steel and 4340 steel are used commercially to make quenched round bars of about the same diameter, such as 1 in. Often, these are fully quenched.
