p11.49 Two steel beams support a concentrated load P = 45 kN,
as shown in Figure P11.49/50. Beam (1) is supported by a fixed
support at A and by a simply supported beam (2) at D. In the unloaded
condition, beam (1) touches, but exerts no force on, beam (2).
The beam lengths are a = 4.0 m, b = 1.5 m, and L 2 = 6 m. The
flexural rigidities of the beams are EI 1 = 40,000 kN · m 2 and EI 2 =
14,000 kN · m 2 . Determine the deflection of beam (1) (a) at D and
(b) at B.
p11.50 Two steel beams support a concentrated load P = 60 kN,
as shown in Figure P11.49/50. Beam (1) is supported by a fixed
support at A and by a simply supported beam (2) at D. In the unloaded
condition, beam (1) touches, but exerts no force on, beam
(2). The beam lengths are a = 5.0 m, b = 2.0 m, and L 2 = 8 m. The
flexural rigidities of the beams are EI 1 = 40,000 kN · m 2 and EI 2 =
25,000 kN · m 2 . Determine
