1. If a steel rope and a nylon rope of equal lengths are to stretch by equal amounts when subjected to equal tensions, what must be the ratio of their distances?
2.A simple hand operated hydraulic press can generate a pressure of 6.0 X 10^9 N/m^2 . If the system is used to compress a small volume, what fraction of the original volume does the final volume of steel occupy?
1. What distances are you talking about? The rope lengths? Are the cross sectional areas the same?
2. What material is being comoressed?
