Calculate the moment of inertia Id for a W 12 × 50 wide-flange section with respect to a diagonal passing through the centroid and two outside corners of the flanges. (Use the dimensions and properties given in Table E-1.)
just after launch from the earth the space-shuttle orbiter is in the 28 x 168-mi orbit shown. at the apogee point a its
Determine the mass fractions of alpha and beta phases, Determine the mass fractions of primary beta and eutectic microconstituents, Determine the mass fraction of eutectic beta
a 5-lb roast initial at 70degf is placed in an oven at 350degf. you may assume the heat transfer coefficient is 2.5
Calculate the specific enthalpy at the compressor outlet. Include in your calculations the changes in kinetic and potential energy.
Write a MATLAB program that can calculate the cross-sectional areas for the rectangle, solid circle, hollow circle, solid semicircle and right triangle shapes. The program should allow the user to enter the dimensions SI and ips units, and give the r..
An aluminium bar is subjected to uniaxial tensile loading. If the lateral strain (perpendicular to the load direction) is measured to be -0.00025, determine the axial stress required to induce this strain (round to the nearest ksi).
Steam with a mass flow rate of 200,000 lb/hr enters a well insulated turbine at 1100 psi, 900degreeF through a duct with a flow area of 1ft^2. A portion of the steam is extracted at p=130psi,T=380degreeF and exits through a 1 ft diameter duct at v=60..
A 50 kg hot iron block is dropped into a relatively cold lake at temperature T. During thermal equilibrium the lake receives Q amount of heat from the iron block. Show that the entropy change of the lake is Q/T starting with an expression for the spe..
Four gold mines in a mountainous region have been in continuous operation for five years. The output is measured in tons, and it has been declining each year in each mine. Estimate the output in each mine after ten years
Using the thermodata computed from the matlab functions to compute the mixture-averaged mass specific Gibbs free energy of the final mixture, as a function of the progress variable (normalized as: 0 for no dissociation, and 1 for complete dissociatio..
consider a regenerative cycle utilizing steam as the working fluid. steam enters the turbine at 3.5 mpa 400oc and
A 2-D reducing bend (of unit width w) is shown below. Note that flow enters the bend at section 1 with a linear velocity profile, but at sections 2 and 3 is uniform. Find the velocity at section 3.
