The slope of the linear portion of the stress vs strain curve from an unconfined compression test is called? a. Poisson's Ratio b. failure Slope c. shear Modulus d. Young's modulus

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
