To manufacture a piston with a circular cross section, an alloy steel bar is required whose length is fixed and has a value of 35 cm and must withstand a compression load of 5.2 tons. For its design, a safety factor of 4/5 is suggested with respect to the yield stress. The shear modulus for that alloy is 80 GPa.To know the resistance of this steel alloy, a compression test was carried out on a specimen of the same material, from this test the data table of stress against engineering deformation shown was obtained.

Calculate a thermal resistance of a copper tube (d1 = 0.192 mm, d2 = 0.208 mm, λ = 310 W/mK) with a Styrofoam layer of di = 0.070 mm.
Two steel bars (Es = 200 GPa and αs = 11.7 × 10-6/°C) are used to reinforce a brass bar (Eb = 105 GPa and αb = 20.9 × 10-6/°C). When the steel bars were fabricated, the distance between the centers of the holes that were to fit on the pins was made 0.5 mm smaller than the 2 m needed. The steel bars were then placed in an oven to increase their length so that they would just fit on the pins. Following fabrication, the temperature in the steel bars dropped back to room temperature. Determine the maximum load P that may be applied to the brass bar if the allowable stress in the steel bars is 29 MPa and the allowable stress in the brass bar is 25 MPa.
