A solid square rod is cantilevered at one end. The rod is 1 m long and supports a completely reversing transverse load at the other end of ±1.5 kN. The material is AISI 1080 hot-rolled steel. If the rod must support this load for 4 × 104 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentrations at the support end.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

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
