1. Calculate the angle of the bars for the following trusses. Use the node with the lowest label number as the starting node. 1 1 45° 45° 3 Node numbers in black, bar numbers in red 45° 4 3 2 1 2 1 2. For both trusses, what would be the size of the global matrix equations and where would the local systems go into the global system. Assume the global system of displacements are ordered in order of their node numbers. NOTE: Remember that the local systems go into the 3. For both trusses, if all bars are made of the same material and have the same cross sectional area, and a force of 5kN is applied to node 2 in the positive x-direction. Can any of these problems be reduced by symmetry?

I having a problem with my code in MATLAB. In the following code results for r is just a 1x3 matrix. Although inside the while loop r equals to multiple 1x3 matrices. I need r equal to one matrix that is of size 27032x3. So, I just need the multiple r matrices to merge together to get one big matrix. I need that matrix to retain its value outside the while loop as well.   cc=0; % set line counter JD = 2460626.666667;   fid = fopen('tle_catalog.txt'); % load the TLE   tline2='gg'; while ischar(tline2) cc = cc+1; % counter name = fgets(fid);% for the ones with three lines tline1 = fgets(fid); % collect first line of two line elements tline2 = fgets(fid); % collect second line of two line elements   if tline2>0 % stop at the end of the file % initialize the propagation [satrec, startmfe, stopmfe, deltamin] ... = twoline2rv(721, tline1, tline2, 'c', 'd');   time_JD = tline1(21:32); yeardayhour = str2double(regexp(tline1, '(\d{2})(\d{3})(\.\d+)', 'tokens', 'once')); dn =…

A frame moves along its n-axis a distance of 2 units and is then rotated about the o-axis an angle 60° followed by a rotation about the z-axis by 90°. It was then translated about the a-axis by 2 units and finally rotated about the x-axis by 45°.  Construct the transformation matrix equation. Compute the total transformation performed by the frame. Compute the joint variables that had to be made if similar location and orientation were to be created using cylindrical and RPY configuration. The initial point is located at P=[5 3 4]^T

Consider the figure as shown below. O-XoYoZo is the reference frame and O-X₁Y₁Z₁ is the frame attached to the tool. Sketch the tool position after each intermediate position of the operation of the tool about the reference frame: roll π/2(rotate about Zo), pitch -T/2(rotate about Yo), yaw π/2(rotate about Xo). Please write the final rotation matrix expression. ZI,Zo XI,Xo Yı, Yo

a 02 02 R₁ ground d R3 b For the 3Bar Inverted Crank Slider shown, 1. Starting with the position equation R=Au, where A is the rotation matrix about the z axis and u is a point on the position vector, derive the velocity equations in both algebraic and matrix form to solve for w3 and b. What are the vector position and velocity equations? Your matrix equation must be in the form [ BH] 2. From part 1 derive the matrix equation to solve for @3 and b. B-[%]-[ ]] B: 3. With the values R₂ = 2 in, R3 = 10 in, R₁ = 8 in, 0₂ = 40°, 03 = 185° and w2= 10 rad/sec. solve for @3 and b. B -7--0 Do not forget units.

Points for stress vs strain (in image) Assume the compressive concrete strength (f’c) is 3,000 lb/in2 (psi)Calculate a cubic function (3rd order polynomial – Ax3+Bx2+Cx+Constant)Use this function to create a function that describes the slope of the cubic function (the derivative of thecubic function). This new function allows you to calculate the tangent to any point along the curve. Thetangent is the modulus of elasticity (E).   The concrete code provides a formula to calculate E for concrete. That formula is:E = 57,000√??′, where f’c is in units of psi, and E is in units of psi.Use the derivative function you calculated to locate the point on the curve where the slope of the curvematches E using the concrete code formula. Express that stress point on the curve as a percentage ofthe compressive strength of the concrete. Now, calculate the secant modulus for the test case using 1,500 psi (50% f’c) as the arbitrary point onthe curve.Assume fracture occurs at the last point…
