Determine the maximum load P that can be applied to the structure without buckling failure. Bar AB has a square section of 8 mm on each side and bar BC has a circular section, with
a radius of 6 mm. Both bars are made of steel, with a modulus of elasticity E = 200 GPa.
The dimensions of the drawing are given in millimeters.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?
