A continuous-fiber composite is loaded axially, in the direction of fiber alignment. In this case, we may model the fiber and matrix as two materials in parallel: the two materials "share" the applied load F , so that F = Ff +Fm; and the two materials experience the same normal strain in the direction of the applied load. Develop an expression for the effective elastic modulus of the composite material in terms of the moduli and volume fractions of its fiber and matrix constituents.
A Brayton gas turbine cycle has two stages of compression and two stages of expansion. The pressure ratio across each stage of the compressor and turbine is 3. The air enters each stage of the compressor at 300K and each stage of the turbine at 1200K..
The uniform, 20-kg bar is placed between two vertical surfaces. Assuming sufficient friction at A to support the bar, find the magnitudes of the reactions at A and B.
at a particular location in the ocean the temperature near the surface is 80of and the temperature at a depth of 1500
Presently, benzene vapors are condensed in a heat exchanger using cooling water. The benzene (100 kmol/h) enters at 0.1013 MPa and 120°C, and exits at 0.1013 MPa and 50°C. Cooling water enters at 10°C and exits at 40°C. What is the current demand for..
What conclusions do you draw from these readings? Can you estimate a standard deviation for the pressure gage?
If the metal sheet is moving at a steady velocity of 10 m/min, determine the required rate of heat removal from the oil to keep its temperature constant at 45°C.
Teresa measures the distance that a traverse system moves an object for a given computer-controlled input pulse. She makes 100 readings, and the mean value is 6.832 m with a sample standard deviation of 1.0 cm. The errors in the measurements are assu..
Determine the maximum bearing force as the airplane undergoes a pullout on a 1830-m-radius curve at a constant airplane speed of 966 km/h and an engine rotor speed of 10,000 rpm, Include the effect of centrifugal force due to the pullout as well a..
a compressor is used to compress air from 1 bar and 290 k to 10 bar. the compression can be assumed to be adiabatic and
