As electric current moves through a wire, as shown in the figure, heat generated by resistance is conducted through a layer of insulation and then convected to the surrounding air. The steady-state temperature of the wire can be computed as T = T_air + q/2 pi [1/k ln (r_w + r_i/r_w) + 1/h 1/r_w + r_i] Determine the thickness of insulation, r_i (meters) that minimizes the wire's temperature given the following parameters q = heat generation rate = 75 W/m r_w = wire radius = 6mm k = thermal conductivity of the insulation = 0.17 W/(mK) h = convective heat transfer coefficient = 12 W/(m^2K) T_air = air temperature = 293 K Notice that the information is not presented in consistent units. Be sure to change the radius of the wire and the thickness of the insulation to meters! a) Plot the function to determine approximately where the minimum occurs b) Use the built-in MATLAB function, fminbnd, to find the minimum
