Study how changes in boundary temperatures on a steel plate affect the temperatures at interior points on the plate. Complete parts (a) through (c) below. 0° Plate A interior temperatures = (0.000 (Type integers or decimals. Do not include the degree symbol in your answers.) 0° Plate A 20° 20° 11 4 20° 12 13 20° 0° 2° 0° 2° Plate B 0° 0° 11 14 2° 12 13 2° 31° 2° 31° 2° Plate C 20⁰ 20° 11 14 12 13 22° 22° 31° 31° a. Begin by estimating the temperature T₁, T₂, T3, T4 at the sets of four points on the steel plates A and B shown in the figure. In each case, the value of Tk is approximated by the average of the temperatures at the four closest points. The answer should be in the form (T₁, T2, T3, T4).
