A bronze bar is fastened between a steel bar and an aluminum bar as shown in Fig. Axail loads are applied at the positions indicated. Find the largest value of P that not exceed an overall deformation of 0.1 mm, or the following stresses: 140 MPa in the steel, 120 MPa in the bronze, and 80 MPa in the aluminum. Assume that the assembley is suitablly barced to prevent buckling. Use E = 200 GPa for steel, E-83 GPa for bronze, and E= 70 GPa for aluminum.

Task 1: Your first customer asked for an internal combustion engine to use it in a designed car. Your role is to describe the operation sequence of different types of available engines, explain their mechanical efficiency, and deliver a detailed technical report which includes the following steps: Describe with the aid of diagrams the operational sequence of four stroke spark ignition and four stroke compression ignition engines. Review the efficiency of ideal heat engines operating on the Otto and Diesel cycles by explaining and generating plot(s) for thermal efficiency, 7 vs compression ratio and cut-off ratio.

Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing, leading to an overload in the motor and a fire in your home. The fire spreads, burning half of Everglades National Park in the worst environmental disaster in US history. The printer company blames you! Stating that you must have been misusing the printer some- how. Use your engineering knowledge to "show those jerks you mean business!" You investigate and find a serial number on the gears and type it into Google, finding the company that manufactures the gears. Their website provides some info that this series of gear is made from AISI 4340 steel and the yield strength is 125 kpsi. Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they are liable for the fire. oct # Gear Information Gear radius (r): 1.00 in Tooth length (1): 0.15 in Tooth height (h): 0.15 in Tooth thickness (b): 0.1 in Angular velocity (w): 0.1 rad/s Motor Information Power (H): 0.009 hp 1…
