The section of the sealed joint shown in the figure is loaded by a force cycling between 4and 6 kips. The members have E 5 16 Mpsi. All bolts have been carefully preloaded to Fi 525 kip each. (a) Determine the yielding factor of safety.(b) Determine the overload factor of safety.(c) Determine the factor of safety based on joint separation.(d) Determine the fatigue factor of safety using the Goodman criterion.

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 there are in a side view Command Window: >> [X,Y] = meshgrid(10:.5:10); >> R = sqrt(X.^2+Y.^2); >> Z = sin(R)./R; >> surf(Z) Curve Fitting Calculate the line of best fit for the points: (5,9) (4,7) (3,5) (2,4) (1,2) Data To Fit
