Question
A square plastic bar (length LP,side dimension sp=193 mm) is inserted inside a hollow.square cast iron tube (length Le
= 400 mm. side sc=200 mm,and thickness tc=3 mm).
(A)What is the required initial length L,of the plastic bar so that.ilcn it is compressed by some force the final length of bar and tube are equal to length L and,at the same time, the gap beten plastic bar and cast iron tube is closed?
(B) Compare initial and final volumes for the plastic bar. Assume that E = 170 GP E,= 2.1GPa.v = 0.3.and = 0.4.
