Acircular bar is 800mm in length and 32mm in diameter. the bar is made from a material with a modulus of elasticity e = 150 gpa and poisson’s ratio of 0.27. when a force is applied to the bar, it extends by 0.7mm. what is the change in diameter and the force applied?

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
