I need help with these two problems im completely stuck

NAME: LAB SECTION HW4P2 (20 points) Solving a system of equations in MATLAB: The following two applications show how a system of linear equation is important in solving engineering problems: The electrical circuit shown consists of resistors and voltage sources. Using Kirchhoff's law, the following system of equations can be obtained: V + Rel: + R, (1, - 2) = 0 LMLw Rz1+R.(iz - y) + R. (-) + R, (1 - 1) = 0 -V+ Rss + Rolls-1) + R.(-i) = 0 V + R -1) + Rolls - () + Rgle = 0 Where vectors V and Rare V = [28 36 42] R = (16 10 6 12 8 14 4 5]. Substitute the values of Vand R in the system of equations. 3000 lb II. For the truss (structure) shown in Figure, the forces in the members can be determined by solving the following system of equations. 16ON F cos 30 + F2 = 3000, Fysin 30 = -6467, -F, cos 30 - Fcos 60 + Fs cos 60 + Focos 30 = -3000, -F, sin 30 - Fysin 60 - Fs sin 60 - F, sin 30 = 0, -F- Fs cos 60 + F, = 0, Fosin 30 = -7533, Focos 30 + F = 0. Rewrite each system of linear equations in the format Ax = b. where x is the column vector of is and Fs, respectively. Write a MATLAB script file HW4P2.m to solve these systems using: a. Left division to find x; EAS 230 - Spring 2020 - HW04 NAME: OLAB SECTION: b. Inverse matrix to find xa h c. If the system is rewritten in the formaty C = d, determine numerically in MATLAB, C and d; d. Use right division to find y; e. Use the inverse matrix to find y. f. Show the output of a, b, c, d and e in the command window. Note: For the Circuit system, negative currents means opposite to the proposed direction in Figure. For the truss system, positive forces means tension while negative means compression. EV 375 Set Wort Ozodob das otpa l lot DODE OED - = - ODBER DE 200 Date 20- or not to r owd
