A large tower is to be supported by a series of steel wires. It is estimated that the load on each wire will be 11,100 N. Determine the minimum required wire diameter assuming a factor of safety of 2 and a yield strength of 1030 MPa.

Explanation:

The given data is as follows.

       Load on each wire = 11,100 N

       Factor of safety (N) = 2

        = 1030 MPa  (150,000 Psi)

Now,

                        =

                        = 515 MPa  (75,000 Psi)

So, we will calculate the diameter as follows.

or,            

                  = 27.45

                         d = 5.24 mm

Thus, we can conclude that the minimum required wire diameter is 5.24 mm.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
