Problem 11 Find the waste in cutting the strongest square timber from a circular log of uniform diameter 2 ft. and length 8 ft.
Solution 11
$2x^2 = 4$
$x^2 = 2$
$V_{waste} = V_{log} - V_{timber}$
$V_{waste} = \frac{1}{4}\pi d^2 L - x^2 L$
$V_{waste} = \frac{1}{4}\pi (2^2)(8) - 2(8)$
$V_{waste} = 9.1327 ~ \text{ft.}^3$ answer
