A. Provide a schematic to explain direct shear test. b. Present an example of shear strength applied in geotechnical engineering design (must include the schematic and explanation)
c. Following are the results of three drained direct shear tests conducted on clay. Graphically and analytically, determine the drained angle of friction and cohesion for the clayey soil.

Normally Stress(kpa) Shear Stress(kPa)

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

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

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
