A square plastic bar (Length Lp,side dimension Sp=193mm) is inserted inside a hollow.Square cast iron tube (length Lc=400 mm .side Sc=200ER mm ,and thickness tc=3 mm). (a) What is the required initial length Lp of the plastic bar so that ,when it is compressed by some force P the final length of bar and tube are equal to length Le and, at the same time ,the gap between plastic bar and cast iron tube is closed? (b) Compare initial and final volumes for plastic bar. Assume that Ec=170 Gpa ,Ep=2.1 GPa, vc=0.3, and vp=0.4
