Construction Mishap The guy wire AB in a frame below is originally unstretched. A contractor accidentally hits the frame with an excavator and tilts the frame by 2 degrees. Determine the approximate normal strain in the wire when the frame is in the deformed condition. Assume the columns are rigid and rotate about their lower supports.

During a steady flow process, the change of energy with respect to time is zero. 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

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
