Farmer Ed has 950 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If Farmer Ed does not fence the side along the river, find the length and width of the plot that will maximize the area. What is the largest area that can be enclosed? 950 - 2x The width, labeled x in the figure, is meters. (Type an integer or decimal.) The length, labeled 950 - 2x in the figure, is meters....

Consider the following problem: A farmer with 950 ft of fencing wants to enclose a rectangular area and then divide it into four pens with fencing parallel to one side of the rectangle. What is the largest possible total area of the four pens? (a) Draw several diagrams illustrating the situation, some with shallow, wide pens and some with deep, narrow pens. Find the total areas of these configurations. Does it appear that there is a maximum area? If so,...

And governing equation used
Written A rectangular plane wing can be treated as a two-dimensional domain as a rough approximation. The length of the wing is 3 and its width (the height of the domain when represented on a sheet of paper) is 1. The wing is exposed to a heat source at its leftmost edge, with a temperature equal to Trot. The flux of heat in the wing is given by Fourier's law: and throughout the domain a source...

A bridge is supported by two types of rectangular cross-section piles located in a river as shown in Figure 1. The width of the piles is w - 0.5 m and their lengths are either l 2 m or 12 2.5 m. The river of depth of about 20 m runs at 2 m/s. Water density is p 1000 kg/m and its absolute viscosity 1.00 x 10-3 N.s/m2 You are asked to perform dimensional analysis to find the drag force...
