PROBLEM 10.40 Solve Problem 10.39 assuming that 1.26 kips, P = 10 in., l = and 150 lb ft/rad K =⋅ . Obtain answers in each of the following quadrants: 09 0 , θ <<° 270 360 , °< < ° and 360 450 . < ° SOLUTION Using Equation (1) of Problem 10.39 and 1.26 kip, 10 in., and 150 lb ft/rad Pl K == = we have () 10 in. 1260 lb 12 in./ft cos 150 lb ft/rad    = or 7 or 7cos cos (1) The solutions to this equation can be shown graphically using any appropriate graphing tool, such as Maple, with the command: { } plot theta, 7 * cos theta , 0..5 * Pi/2 ; t = Thus, we plot and 7cos in the range
