The jib crane is oriented so that the boom DA is parallel to the x axis. At the instant shown, the tension in cable AB is 13 kN. Determine the moment about each of the coordinate axes of the force exerted on A by the cable AB.

AFTER MIDTERM 2 3RD last week 3D plotting Create matrices for X and Y like this: [X,Y] = meshgrid(10:.5:10); The variables are then available to use in equations: R = sqrt(X.^2+Y.^2); Z = sin(R)./R; The “n” in the syntax for contour are for how many lines...
