b. Two metallic rods A and B with similar length and cross sectional area are joined together and all curved surfaces are insulated. At steady state, the temperatures at their ends are shown in the figure below. The thermal conductivity of A is twice that of B. Calculate the temperature at the junction of these rods.
thermal conductivity is equal on both A and B
area A and B EQUAL
TEMPERATURE A=90 degree celcius
temperature b = 30 degree celcius
temperature diff=60 degree celcius.
