Show that the line PQ is perpendicular bisector of AB .Three identical rods AB,CD and PQ are joined as shown. P and Q are mid points of AB and CD respectively. Ends A,B,C and D are maintained at 0^∘C, 100^∘C, 30^∘C and 60^∘C respectively. The direction of heat flow in PQ is :1. ABCD is a quadrilateral in which P, Q, R and S are mid-points of the sides AB, BC, CD and DA (see Fig 8.29). AC is a diagonal. Show that: (i) SR || AC and SR = 1/2 AC (ii) PQ = SR (iii) PQRS is a parallelogram.
