NARRATIVE
         The elastic limit apparatus consists of a length of transformer wire wrapped around a shaft with an attached indicator needle. Increasing masses of 2 Kg weights are hung on the wire and then removed showing that the elasticity of the wire causes the needle to return to its original position. The elastic limit is reached when about 12 Kg are hung on the wire. Start with about 6 Kg.
