The global deformations can be found from the global stiffness Equa-
tion 4.36 (step 4). The rows and columns corresponding to the support
constraint degrees of freedom must be deleted prior to the solution. This
would be all three motions at 1 and 4. The resulting matrix is just joints 2
and 3. This is shown in Table 4.6 along with the reduced load. The solution
for the deformations will be in inches and radians.
