Five rods of same material and same cross-section are joined as shown. Lengths of rods ab, ad and bc are l, 2l and 3l respectively. Ends a and c are maintained at temperatures `200^(@)C` and `0^(@)C` respectivelly.

For what length x of rod dc there will be no heat flow through rod bd ?

Five rods of same material and same cross-section are joined as shown. Lengths of rods ab, ad and bc are l, 2l and 3l respectively. Ends a and c are maintained at temperatures 200^(@)C and 0^(@)C respectivelly. If x has the value calculated in the above question. Then temperature of junction b or d is

Three rods of same material and having the same cross-section are joined as shown in the figure.The tremperature of junction of three rods is : .

Three conducting rods AB, BC and BO made of same material and same cross section are arranged as shown in the figure. Temperatures at the points A, O and C are maintained at 20^(0)C, 90^(0) C and 0^(0) C respectively. The ratio of lengths of BO to BC when there is no beat flow in AB, is

Three rods AB,BC and BD made of the same materical and having the same area of cross section have been joined as shown is the The ends A,C and D are held at temperatures 20^(@)C Cand 80^(@)C respectively If each rod is of same length then find the temperature at the junction B of the three rods .

Three rods made of same material and having the same cross-section have been joined as shown in fig. each rod is of the same length. The left and the right ends are kept at 0^(@)C and 90^(@)C respectively. What will be the temperature of the junction of the three rods?

Three rods made of same material and having the same cross-section have been joined as shown. In the figure.Each rod is of the same length. The left and right ends are kept at 0^@C and 90^@C respectively. The temperature of the junction of the three rods will be

Two ends of a conducting rod of varying cross-section are maintained at 200^(@)C and 0^(@)C respectively. In steady state:
