The change in yield strength as a function of temperature is
given in the same form as equation 2.13 in the textbook (posted
picture). where sigma_o = yield strength at room temperature, 'a' =
1 and the melting point (Tm) of the 7075 alloy is 873 K. Calculate
the maximum operating temperature of the spacecraft before the
alloy will start to yield.

1. Chemical reaction rates are proportional to a rate constant, k, which changes with temperature according to the equation : For a certain reaction: Q = 8000 cal/mole R = 1987cal/mole K k0 = 1200 min-1 k = k0·e–Q/(R·T) Find the values of k for temperatures from 100K to 500K in 50-degree increments. Create a table for your results. The table should contain two columns, with left column containing the temperatures and the right column containing the correcsponding values of...

A long wire with circular cross section and diameter D = 1 mm is submerged in an oil bath with temperature To 20。C. The wire is initially at temperature T = 20。C, the same temperature as the oil. A current is passed through the wire, resulting in a volumetric heat generation of q - 1.5 x 108 W/m3. The convection coefficient is h - 500 W/m2 - K, and the properties of the wire are ρ-8000 kg/m3, Cp-500 J/kg-K, and...

Temperature Change and Phase Change - Specific Heat and Latent Heat - From COLD ICE to Warm Water The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat which depends on the material and phase (for exmample, water and ice have different specific heat). The specific heat...

M 6. The equation for logistic growth has the general form y = 1+ Be-M -M , where M, B, and k are positive constants and M represents the maximum level that y can obtain. Suppose that a lake is stocked with 100 fish. After 3 months there are 250 fish. A study of the ecology of the lake predicts that the lake can support 1000 fish. Find a logistic function for the number NO) of fish in the lake...

A major objective in advancing gas turbine engine technologies is to increase the temperature limit associated with operation of the gas turbine blades. This limit determines the permissible turbine gas inlet temperature, which, in turn. strongly influences overall system performance. In addition to fabricating turbine blades from special, high-temperature, high-strength superalloys, it is common to use internal cooling by machining flow channels within the blades and routing air through the channels. We wish to assess the effect of such a...
