Astrain gauge that has a nominal resistance of 350 w and a gauge factor of 1.8 is mounted in an equal-arm wheatstone bridge (equal-arm means that the other 3 resistors also have a 350 w resistance. these 3 resistors are not strain gauges). this strain gauge is mounted to sense axial strain. the bridge output voltage is 1 mv and the input voltage is 5 v. what is the axial strain measured by the strain gauge? if we also have strain in the transverse direction (perpendicular to the axial direction) and this strain is 15% of the axial one, what is the error in the previous axial strain due to a transverse sensitivity of the gauge of 0.05? the gauge factor of 1.8 was obtained from a tensile test on a steel specimen (poisson’s ratio = 0.27).

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
