Agroup of engineers has just conducted an experimental trial on a shoe desined to people suffering from a painful foot disorder. during the trial the shoe proved effective for only 5% of the test subjects. what should the engineers do next?

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

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

Around steel bar, made from material with a yield stress of 750mpa, is loaded so that it has stresses co locations of maximum normal stress and maximum shear stress. use maximum shear stress and maximum distortion energy theories to calculate the safety factors for initial yielding failures.
