Упражнение 5
Представьте, что у вас в руках прямоугольный лист картона, ножницы и скотч. Ваша цель – смастерить коробочку следующим способом: вырезать квадратные уголки (1), сделать сгибы вдоль пунктирных линий до соединения ребер $a$ и $b$ (2), склеить соединенные ребра скотчем и полюбоваться на свое изделие (3) (рис. 1).
1) 2) 3)
Рис. 1
Если размер вырезаемых квадратов будет очень мал, то получится очень плоская коробка. Если сторона квадратика будет чуть меньше половины меньшей стороны прямоугольника, то коробка получится очень узкой. Практический вопрос: как из данного прямоугольника получить коробку максимального объема?
Упражнение 5
Возьмите нитку или веревку длиной не более 1 м и свяжите концы. Постарайтесь расположить ее на столе так, чтобы площадь, огороженная ниткой, оказалась наибольшей. Какая фигура получилась?
Решение 2 (rus). №5 (с. 106)
Как из данного прямоугольника получить коробку максимального объема?
Это классическая задача на оптимизацию, для решения которой используется математический анализ. Пусть исходный лист картона имеет длину $L$ и ширину $W$. Мы вырезаем из каждого угла одинаковые квадраты со стороной $x$. После этого мы сгибаем боковые стороны вверх, получая открытую коробку.
Размеры полученной коробки будут следующими: высота равна $h=x$, длина основания $l = L - 2x$, а ширина основания $w = W - 2x$. Объем коробки $V$ как функция от $x$ выражается формулой: $V(x) = l \cdot w \cdot h = (L - 2x)(W - 2x)x$. Чтобы размеры коробки были физически возможными, сторона вырезаемого квадрата $x$ должна быть больше нуля, но меньше половины меньшей стороны листа, то есть $0 < x < \frac{\min(L, W)}{2}$.
Для нахождения значения $x$, при котором объем $V(x)$ будет максимальным, необходимо найти производную функции $V(x)$ по переменной $x$ и приравнять ее к нулю. Раскроем скобки в выражении для объема: $V(x) = (LW - 2Lx - 2Wx + 4x^2)x = 4x^3 - 2(L+W)x^2 + LWx$.
Теперь найдем производную: $V'(x) = \frac{d}{dx}(4x^3 - 2(L+W)x^2 + LWx) = 12x^2 - 4(L+W)x + LW$.
Приравняем производную к нулю для поиска критических точек, в которых объем может достигать экстремума (максимума или минимума): $12x^2 - 4(L+W)x + LW = 0$.
Это квадратное уравнение относительно $x$. Решив его, мы получим два корня: $x = \frac{L+W \pm \sqrt{(L+W)^2 - 3LW}}{6} = \frac{L+W \pm \sqrt{L^2 - LW + W^2}}{6}$.
Один из корней, $x_1 = \frac{L+W + \sqrt{L^2 - LW + W^2}}{6}$, не подходит, так как он приводит к значению $x$, которое больше половины меньшей стороны листа, что физически невозможно. Второй корень, $x_2 = \frac{L+W - \sqrt{L^2 - LW + W^2}}{6}$, удовлетворяет нашим ограничениям. Именно при таком значении стороны вырезаемого квадрата объем коробки будет максимальным.
Ответ: Для получения коробки максимального объема необходимо вырезать из углов прямоугольника квадраты, сторона которых $x$ вычисляется по формуле: $x = \frac{L+W - \sqrt{L^2 - LW + W^2}}{6}$, где $L$ и $W$ — это длина и ширина исходного листа.
Упражнение 5
Вопрос заключается в том, какую форму нужно придать замкнутой кривой фиксированной длины (в данном случае, нитке), чтобы она огораживала максимально возможную площадь. Эта задача известна в математике как изопериметрическая задача.
Решением этой задачи является круг. Согласно изопериметрической теореме, среди всех плоских фигур с одинаковым периметром наибольшую площадь имеет именно круг. Любая другая фигура с таким же периметром, будь то квадрат, прямоугольник, треугольник или любая другая сложная форма, будет иметь меньшую площадь.
Таким образом, чтобы расположить нитку на столе и получить наибольшую площадь, ее следует уложить в форме окружности.
Ответ: Получилась фигура - круг.
