Ahollow circular steel strut with its ends position fixed has a length of 2.5m, its external diameter being 10 cm and its internal diameter is 8.8 cm. before, loading, the strut is bent with a maximum deviation of 0 45 cm: assuming that the centre line ofthe strut is sinusoidal, determine the maximum stress due to a central compressive end load of 10 kn. take e 210 gpa.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

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

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
