For the given frames (1) – (2) below, 1) determine reactions at A and B; 2) draw axial force N, shear force V, and moment M diagrams of the frame (1) and (2); 3) determine the internal forces at the cross-section 1 and 2 for Problem (2).

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
