Use Newton Raphson (NR) method to find the solution to the following equations, using the initial values of v=0.75, @= 0.5, r = 0.5. 2 1(3-2)2p=45 1 v 21-P 2 1 (1+2) wr=2.5 207=0.5. These equations arise in the modelling of stress on a turbine rotor. (a) What is the Jacobian matric for the above equations? (b) Show hand calculation for the 1st three iterations. Note: you can use any matrix reduction method to solve this by hand (c) Use MATLAB to solve the equations using NR, and continue the iterations until Ea
