Problem 6: Solve for the reactions at Points A and D, and find the axial force...
PROBLEM 01 Use the equations of equilibrium to find the external reactions at Points A and C. Next solve for the internal forces in individual truss members using the "method of joints". Show the component (x & y) forces for each member on the provided worksheet. Look for "zero force" members to simplify the problem. Once component forces are solved for diagonal members, use the Pythagorean Theorem to calculate the overall axial tension or compression force for each member. Complete...
