Measure and graph the strain vs. stress curve for a long metal wire by hanging weights from the end of the wire and

carefully measuring the stretch as a function of the hanging weight. Determine Young's modulus for this material. If

possible, go beyond the “yield” stress and observe the rapid, large increase in the strain. BE CAREFUL! Once you exceed

the yield stress, the wire may break and dump the weights on whatever is underneath.
