1.	A thin rectangular strip ABCD of thickness d is such that the coefficient of linear expansion ' alpha' of any section of the strip (of the form XY) distant 'x' from the face AB varies as alpha= alpha_(0) + alpha_(1) x. Determine the radius of curvature of the strip when heated through a temperature range Delta T
Answer» `( 1)/( 2 alpha_(1) ( Delta T) ) [2 + ( alpha_(0) + alpha_(1) d) Delta T)` `( 1)/( 2alpha_(1) (Delta T) ) [ 2+ ( 2alpha_(0) + alpha_(1) d) Delta T]` `( 1)/( alpha_(1) ( Delta T) )[ 1+ ( 2alpha_(0) + alpha_(1) d ) Delta T]` `(1)/( alpha_(1) ( Delta T) ) [2 + (alpha_(0) + alpha_(1) d) Delta T]` Answer :B
