The figure below shows a bracket machined from $0\mathrm{.}5-$ in

$-$thick steel flat stock. It is rigidly attached to a support and loaded with P

$=2000$ lb

at point D

$.$

A bracket consists of $3$ segments and has a thickness of $0\mathrm{.}5$ inches. The first segment is horizontal, fixed at its left end, and has a width of $3$ inches. Vertical section A$-$A is marked on the segment at $10$ inches from both its left and right ends. The second segment is vertical and propagates below the first one from its right end. The segment has a half width of $1\mathrm{.}5$ inches and a length of $3$ inches. The right edges of the first two segments lie on the same line. Centerlines of the segments intersect at point C$.$ Horizontal section B$-$B is marked on the second segment at $2\mathrm{.}5$ inches below point C$.$ The third segment is horizontal and propagates to the left from the bottom of the second segment. The segment has a width of $3$ inches and a length of $12$ inches. Right edges of the second and third segments lie on the same line. Section B$-$B is at $5$ inches above the bottom edge of the third segment. Point D is marked on the centerline of the third segment at its left edge. It is $8$ inches to the right of the fixed end of the bracket. Vertical force P acts downward at D$.$
