can you please do problem 2

obl The nodal displacements of the crane shown in Fig. 1 can be found by solving the equilibrium equations, which yield the following system: 170.4105 37.9473-113.8420-37.9473 37.9473 69.217637.9473-12.6491 113.8420 37.9473 120.913 45.0184 37.9473-12.6491 45.0184 19.7202 Where u, i-1.2, 3.4, are the components of nodal displacement (inch) and P is the load applied (lb) along the direction uh 1.2.3.4 1000 Ib 100 50 Y 100" Fig. 1 a) Write a MATLAB Script that calls the GEpivot new function covered in class to find the nodal displacements using Gaussian elimination for the following inputs: P4-1000 Your code should not modify GEpivot new in any way (you should just pass inputs to it and receive outputs from it). Finally, have your code save the variables lu and piv which will be used in Problem #3. This can be done by adding a line like: save prob2output.mat lu piv which will create a file called prob2output.mat (containing lu and piv) that can be loaded by another code. b) What is the maximum nodal displacement and where is it located? Is it a vertical or horizontal displacement? obl The nodal displacements of the crane shown in Fig. 1 can be found by solving the equilibrium equations, which yield the following system: 170.4105 37.9473-113.8420-37.9473 37.9473 69.217637.9473-12.6491 113.8420 37.9473 120.913 45.0184 37.9473-12.6491 45.0184 19.7202 Where u, i-1.2, 3.4, are the components of nodal displacement (inch) and P is the load applied (lb) along the direction uh 1.2.3.4 1000 Ib 100 50 Y 100" Fig. 1 a) Write a MATLAB Script that calls the GEpivot new function covered in class to find the nodal displacements using Gaussian elimination for the following inputs: P4-1000 Your code should not modify GEpivot new in any way (you should just pass inputs to it and receive outputs from it).
