A plastic cylinder is held snugly between a rigid plate and a foundation by two steel bolts

Question:

A plastic cylinder is held snugly between a rigid plate and a foundation by two steel bolts (see figure).
Determine the compressive stress Ïƒp in 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, pitch of the bolt threads p = 1.0 mm, modulus of elasticity for steel Es = 200 GPa, modulus of elasticity for the plastic Ep = 7.5 GPa, cross-sectional area of one bolt As = 36.0 mm2, and cross-sectional area of the plastic cylinder Ap = 960 mm2.
