A timber [E = 1,800 ksi] beam is loaded and supported as shown. The cross section of the timber beam is b = 4 in. wide and h = 7 in. deep. The beam is supported at B by a 0.875-in.-diameter aluminum [E = 10,500 ksi] rod, which has no load before the distributed load is applied to the beam. After a distributed load of w = 610 lb/ft is applied to the beam, determine

(a) the force carried by the aluminum rod.
(b) the maximum bending stress in the timber beam.
(c) the deflection of the beam at B.

Assume LAB = 4 ft, LBC = 13 ft, L1 = 10 ft.



Answers:

(a) F = kips
(b) σ max = ksi
(c) vB = in.
