The formula Wtotal = ΔK refers to the total work by all forces when potential energy functions are not used. Do think very carefully about the angle in the formula W = F*d*cosφ. This is the angle measured between the force and the displacement.

The OLS problem will provide a minimum. Intuitively, a minimum is achieved because the problem is to minimize the sum of squares. Squaring each residual forces each term to be nonnegative. The problem becomes then minimizing the sum of nonnegative numbers. Because all numbers are nonnegative, the smallest possible sum is zero.

If the truss is statically indeterminate, then you will not be able to solve for all of the forces. The trusses 1, 2, and 3 are statically indeterminate based on the formula 2J = M + R. Use the formula to demonstrate that each truss is statically indeterminate, then sketch a solution that would result in the truss being statically determinate.
