The length of the longest ladder that can negotiate the corner depicted in Fig. P15.17 can be determined by computing the value of u that minimizes the following function:
For the case where w1 = w2 = 2 m, use a numerical method (including software) to develop a plot of L versus a range of α s from 45o to 135o.
