Chapter 10, Problem 26P

To determine

The estimated mass of each leg is to be determined.

Answer to Problem 26P

The estimate mss of each leg is $12Kg$ .

Explanation of Solution

Given info:

Apparent mass, $M_{app}=54kg$

Actual mass, $M_{actual}=78kg$

  $SG=1.00$

Formula used:

  $massofdisplacedwater=M_{actual}-M_{app}$

And,

  $\rho =\frac{m}{V}$

Calculation:

Now substitute the given values in the formula,

  $massofdisplacedwater=78-54=24kg$

And,

  $V=\frac{24}{\rho }=\frac{24}{1000}=0.024m^3$

Since the legs having equal density as the water, therefore, each one must displace the $0.012m^3$

So, the mass is,

  $m=V\rho =0.012\times 1000=12Kg$Conclusion:

The mass is $12Kg$ .
