Passage - II: Two rods of different metals having the same area of cross section A are placed between the two massive walls as shown in Fig. The first rod has a length l coefficient of linear expansion alpha_(1) and Young's modulus Y_(1). The corresponding quantities for second rod are l, alpha_2 and Y_2. The temperature of both the rods is now raised by t^(@) C. Find the force with which the rods act on each other (at higher temperature) in terms of given quantities

Find the force with which the rods act on each other (at higher temperature) in terms of given quantities
Answer» `(A(alpha_1+ alpha_2) t y_(1) t_(2) )/( y_(1) + y_(2) )` `(Ay_(1) y_(2) ( alpha_(1) + alpha_(2) ) )/( 4 (y_(1) + y_(2) ) )` `( A( y_(1) + y_(2) ) alpha_(1) alpha_(2) )/( alpha_(1) + alpha_(2) )` `( A ( alpha_(1) + alpha_(2) ) )/( (y_(1) + y_(2) ))` Answer :A
