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.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
