Problem 3.136

The forces and couples shown are applied to two screws as a piece of sheet metal is fastened to a block of wood. Reduce the forces and the couples to an equivalent wrench and determine (a) the resultant force R, (b) the pitch of the wrench, (c) the point where the axis of the wrench intersects the xz-plane.

Step-by-Step Solution:
Step 1 of 3

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
