1.	If x longitudinal strain is produced in a wire of Young's modulus Y, then potential energy stored in a material of the wire per unit volume is ..........
Answer» `YX ^(2)` `2Yx ^(2)` `(Y^(2) x )/(2)` `(Yx ^(2))/(2)` Solution :POTENTIAL energy stred in a wire per UNIT volume `U =1/2 xx ` stress `xx` strain `=1/2 xx Yxx` strain `xx` strain `[ because Y= ("Stress")/("Strain") ]` `= (Yxx ("strain") ^(2))/(2)` `= (Yx ^(2))/(2)`
