Use the matrix equation
d = Fw, where d =[d1 d2 d3], w =[w1 w2 w3] and F is the 3 × 3 flexibility matrix for the beam, to find the stiffness matrix F−1 and the force matrix w.
The entries of F are measured in inches per pound. 61.
F =[0.008 0.004 0.003 0.004 0.006 0.004 0.003 0.004 0.008],
d =[0.585 0.640 0.835] 62.
F =[0.017 0.010 0.008 0.010 0.012 0.010 0.008 0.010 0.017],
d =[ 0 0.15 0]
