The weight W = 5 lb, the spring constant is k = 5 lb/ft, and the damping constant is c = 0.55 lb-s/fl The spring is unstretched when x = 0. The mass is displaced to the position x = 3 ft and released from rest. (a) What is the natural frequency and damping of the system? (b) If the damping is subcritical what is the frequency of the resulting damped vibrations?

Problem 4. A water reservoir is open at the top, and has radius r 50 ft and wall thickness t 10 in. what height h of the water will produce a circumferential (hoop) stress of 700 psi in the wall of the reservoir? What is the longitudinal (i.e. axial) stress in the wall due to the water? HINT: Water has a weight density of 62 lb/ft3 (so the pressure is caused by the weight of water), and the reservoir is...

Pumping a conical tank A right- circular conical tank, point
down, with top radius 5 ft and height 10 ft is filled with a liquid
whose weight-density is 60 lb/ft^ 3 . How much work does it take to
pump the liquid to a point 2 ft above the tank? If the pump is
driven by a motor rated at 275 ft-lb/sec (1/2 hp), , how long will
it take to empty the tank? Must work the integral out by...

A 5-ft diameter 300-lb circular hatch is located on a submarine,
as shown. The submarine is in sea water with a specific weight of
64 lb/ft3 . Determine the following: (a) the resultant force on the
hatch due to the water pressure (b) the location of the resultant
force (distance below the water surface). (c) the magnitude of the
force, F, which should be applied to open the hatch when it is
submerged as shown. It is hinged at the...

(2) The work required to pump the fluid from a tank (between a units and b units above the bottom of a tank) of constant mass-density p out to a height h above the bottom of the tank is given by W- pg(cross-sectional area at y)(distance fluid at y needs to be lifted) dy where g is the acceleration due to gravity and y is the distance from bottom of the tank. Note: Water has a mass-density of p 10...

5. Hydrogen undergoes a polytropic process with n=0.7 from an initial specific volume of 22 ft3/lb and initial temperature of 200° F to a final specific volume of 16 ft3/lb. The entropy decrease during the process is 7.5 Btu/°R. Model the hydrogen as an ideal gas with constant specific heats. Evaluate the specific heat at 200° F. Determine the mass of the hydrogen.
