Use Rayleigh s method to solve Problem 2.26.
Problem 2.26
A mass m is attached to a cord that is under a tension T, as shown in Fig. 2.67. Assuming that T remains unchanged when the mass is displaced normal to the cord,
(a) write the differential equation of motion for small transverse vibrations and
(b) find the natural frequency of vibration.
a turbine that is well insulated runs on air. at steady state air enters at 0.5 mpa and 727 c and expands
Determine the mean effective pressure (in psia) of an ideal Otto cycle that uses air as the working fluid; its state at the beginning of the compression is 12.9 psia and 65oF; its temperature at the end of the combustion is 1,545oF; and its compressi..
Refrigerant 22 enters the valve of a refrigeration system with a pressure of 14 bars and a temperature of 32 C and exits at a pressure of 4 bars. Neglecting heat transfer and any changes in potential and kinetic energy, determine the quality of the r..
What is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 22°C and -6°C respectively?
water at atmospheric pressure boils on the surface of a large horizontal copper tube. the heat flux is 90 of the
Calcium oxide (CaO) is formed by decomposing limestone (pure CaCO3). In one kiln the reaction goes to 70% completion. What is the composition (by mass) of the solid product (CaO) withdrawn from the kiln? (Hint: there will be two separate product s..
