The illustration would be that of a double replacement reaction.

<h3>What are double replacement reactions?</h3>

They are reactions in which 2 ionic compounds exchange ions to form two new products.

Thus, in the reaction: ab + cd ----------> ad + cb

ab and cd are two ionic compounds. The b in ab is replaced by the d in cd while the d in cd itself is replaced by the b in ab. Hence, new products, ad and cd, are formed.

A cylindrical specimen of some metal alloy having an elastic modulus of 129 GPa and an original cross-sectional diameter of 4.4
miss Akunina [59]

Explanation:

The cross-sectional area of the specimen is calculated as follows.

         A_{o} = \frac{pi}{4} d^{2}

                     = \frac{3.14}{4} \times (\frac{4.4}{1000})^{2}

                     = 1.5197 \times 10^{-5} m^{2}

Equation of stress is as follows.

              \sigma = \frac{F}{A_{o}}

And, the equation of strain is as follows.

             \epsilon = \frac{\Delta l}{l_{o}}

Hence, the Hook's law is as follows.

              E = \frac{\sigma}{\epsilon}

       E = \frac{\frac{F}{A_{o}}}{\frac{\Delta l}{l_{o}}}

          = \frac{F \times l_{o}}{A_{o} \times \Delta l}

or,    l_{o} = \frac{E \times \Delta l \times A_{o}}{F}          

                   = \frac{129 \times 10^{9} \times \frac{0.48}{1000} \times 1.662 \times 10^{-5}}{1570}

                  = 0.6554 m

or,         l_{o} = 655.4 mm

Thus, we can conclude that the maximum length of the specimen before deformation if the maximum allowable elongation is 0.48 mm is 655.4 mm.
