thank you [Music] Hello friends Welcome to our Channel learn physics you'll have the energy Stone instructions sorry act on aware of length L and area of cross section A the increase in length is smaller okay capital okay area of cross sections sorry now this when we are applying Force okay right less okay so Young's modulus right a poor linear stress my linear strain I mean e is equal to um okay sorry [Music] work done total work down uh work done to produce a stretching of oil from zero to L A Minute zero to L have control we integrated work done is equal to integration limit zero to l f into DL foreign um foreign Now volume of the wire okay the area of the cross section into small L character a into L right hence work done per unit volume of the wire okay if one okay um so a capital l okay right volume [Music] the energy stored in the wire is equal to the work done in stretching it okay so on the Wireless in order to deform a body work must be done by the applied force and there on the body deformed I don't know okay on the wire and deformed and the and our Force right the energy spent in store the sorry the energy Sprint is stored up as potential energy in the body so now can the energy on the uh so on the um you know foreign [Music] [Music]
