The flywheel turns clockwise with a constant speed of 670 rev/min, and the connecting rod ab slides through the pivoted collar at c. for the position θ = 57°, determine the angular velocity ωab (positive if counterclockwise, negative if clockwise) of ab by using the relative-velocity relations. (suggestion: choose a point d on ab coincident with c as a reference point whose direction of velocity is known.)

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

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
