Design a minimum-mass support column of fixed height, h + h. the support column of height h has outer and inner diameters do and di, respectively, and uniform thickness t. the support column is treated as a cantilever beam and must withstand bending from uniform wind loads, p = 600 n/m2 on the sign of height h (neglect wind loads on the support column itself) and support the weight of the sign. in addition to the wind load, the sign itself weighs w =2.8 kn/m2.

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
