Write a user-defined MATLAB function that uses classical fourth order Runge-Kutta method to solve a first order ODE problem dydx = f(x, y) in a given interval a ? x ? b with initial condition y(a) = y0 and step size of h. For function name and arguments, use [x,y] = myrk4(f, a, b, h, y0)
Check your function to find the numerical solution for dydx=?1.2y+7e^(?0.3x) in the interval 0 ? x ? 4 with initial condition y(0)=3. Run your program three times for h=1.0, 0.1, 0.01 and plot all results along with analytical solution y=(70/9)*e^(?0.3x)?(43/9)*e^(?1.2x) on the same figure.

The pressure p and volume v of a given mass of gas are connected by the relation
k=(p+a\v^2)(v-b)
where a, b, and k are constants.
Using the composite trapezoidal method, write a MatLab script to approximate the work done by the gas in expanding from an initial volume to a final volume. Express p in terms of v.
Where W = Integral (Pdv)

Regarding the fracture mechanism of metals, polymers and ceramics
(a) Explain why FCC metals show a ductile fracture even at low temperatures while BCC metals do not.
(b) What is crazing? What can you say about the Poisson’s ratio of the crazed material?
(c) Generally, in ceramics, intergranular fracture is preferred to cleavage fracture; however, in metals, transgranular fracture is the preferred mechanism for brittle failure. Why? Use a physical reason supported with an equation in your answer.

13.75 Air enters the compressor of a simple gas turbine power plant at 70F, 1 atm, is compressed adiabatically to 40 lbf/in.2, and then enters the combustion chamber where it burns completely with propane gas (C3H8) entering at 77F, 40 lbf/in.2and a molar flow rate of 1.7 lbmol/h. The combustion products at 1340F, 40 lbf/in.2 enter the turbine and expand adiabatically to a pressure of 1 atm.The isentropic compressor efficiency is 83.3% and the isentropic turbine efficiency is 90%. Determine at steady state
(a) the percent of theoretical air required.
(b) the net power developed, in horsepower.
