Consider the apparatus shown in Figure P18.73a, where the hanging object has mass M and the
string is vibrating in its second harmonic. The vibrating
blade at the left maintains a constant frequency. The wind
begins to blow to the right, applying a constant horizontal
force F
S
on the hanging object. What is the magnitude of
the force the wind must apply to the hanging object so that
the string vibrates in its first harmonic as shown in Figure
18.73b?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
