To use a stress-strain diagram to determine the ultimate stress of a material and to determine the minimum diameters of posts supporting a beam under static loading. As shown, beam ABC is subjected to a load at A that has weight W = 850 kN. The cylindrical posts BD and CE are made of the same material, whose properties are shown in the stress-strain diagram provided. Let a = 8.5 m, b = 6.0 m, r = 5.0 m and s = 8.0 m X Part A - Ultimate stress in compression Using the stress-strain diagram provided, select the ultimate stress for the posts' material when the posts are under compression Part B - Ultimate stress in tension Using the stress-strain diagram provided, select the material's ultimate stress when it is under tension Part C - Minimum diameter of post BD Using the ultimate stress found earlier, determine the minimum diameter of post BD required for the post not to fail Express your answer to three significant figures and include the appropriate units. dup = Value Units Submit Part D - Minimum diameter of post CE Using the ultimate stress found earlier, determine the minimum diameter of post CE required for the post not to fail Express your answer to three significant figures and include the appropriate units.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
