Chapter 2, Problem 2.5.26P
A plastic cylinder is held snugly between a rigid plate and. a foundation by two steel bolts (see figure).
Determine the compressive stress erFin the plastic when the nuts on the steel bolts are tightened by one complete turn.
Data For the assembly are as follows: length L = 200 mm, pilch of the bolt threads p= 1.0 mm, modulus of elasticity for steel Ez= 200 GPa, modulus of elasticity for the plastic Ep = 7.5 GPa, cross-sectional area of one boll As= 36.0mm2, and cross-sectional area of the plastic cylinder Af=960 mm2.
