Note. - It must bo understood and also borne in mind, that, in estimating the amount of tensile strain to which a body is subjected, the weight of the body itself must also be taken into account; for according to its position so may it approximate to us whole weight in tending to produce extension within itself; as in the almost constant application of ropes and chains to great depths, considerable heights, etc.
