Question

Fluids:

3. The fire truck shown in the figure below is parked on an ice covered road. It produces a water jet with a velocity, V 35 which is directed towards the fire as shown. The diameter of the jet is 80 mm and it is positioned on the longitudinal plane of symmetry of the truck. The weight of the truck is 100 kN. The water density, p 996 kg/m3, and the viscosity, 0.00093 kg/ms. Do the following: a) Draw your control volume surface and a free body diagram with all forces acting. b) Determine the horizontal friction force required between the tires and the ice covered road to produce the water jet described. e) Determine the vertical reaction forces on the front and rear tires. d) Determine if the truck will slide on the ice. The coefficient of friction between the tires and the ice, f 0.10. 30° cg 3 m 1.8 m
