Determine the equivalent principle stresses for a stress element in the following state: tension of 100 MPA, in the x direction, compression of 50 MPA in the y direction, and a shear of 30 MPA in the xz plane Answe r Sigma 1 = _ Sigma 2 = _

What precautions should you take to prevent injuries when dealing with heavy loads?

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
