Worksheet provided by your instructor to document your answers. 1. A weight of 20,000 lb. is supported on a rectangular base plate that is 8 in. wide
and 3 ft long. The base plate rests on a concrete slab. Determine the stress that the
base plate exerts on the concrete slab. Express your answer in units of (a) lb/in.2
and (b) lb/ft? (precision of 1 for (a) and of 1000 for (b))

What precautions should you take to prevent injuries when dealing with heavy loads?

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

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
