2.17 Consider a horizontal cantilevered beam that is clamped at one end but free along the remainder of its length. A discrete model of the forces on the beam yields a system of lin- ear equations Az= b, where the n n matrix A has the banded form 9-4 10 0 1461. 1-6 -1 0 01 -2 1 the n-vector b is the known load on the bar (including its own weight), and the n-vector represents the resulting deflection of the bar 2.17 Consider a horizontal cantilevered beam that is clamped at one end but free along the remainder of its length.
