The bottle rests at a distance of 3 ft from the center of the horizontal platform. If the coefficient of static friction between the bottle and the platform is ms = 0.3, determine the maximum speed that the bottle can attain before slipping. Assume the angular motion of the platform is slowly increasing.
a 1.5 in-diameter bar has been machined from a steel 1050 su 100ksi sy 84ksi. this part is to withstand a fluctuating
Water flows from the bottom of a large tank where the pressure is 120 psia to a turbine located 65 ft below the bottom of the tank that produces 40 hp. The pressure at the turbine exit is 42 psia and the water velocity is 36 ft/sec. The flow rate of ..
Dry air passes over a flat plate, at the surface of which the water vapor concentration is 0.01 kmol/m3. The plate’s length is 5m (in the direction of airflow) and its width is 1m, and the free-stream velocity of the air is 2 m/s. If both the convect..
