Tech A says that a cranking compression wet test can indicate whether the cylinder has worn piston rings. Tech B says that the throttle should be held wide open during a cranking compression test. Who is correct

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false
