Question

Transcribed Image Text:A cantilever beam 10 ft long carries a uniformly
distributed load of w= 100 lb/ft. The beam is
constructed from a 3-in.-wide by 8-in.-deep
wood timber (1) that is reinforced on its upper
surface by a 3-in.-wide by 0.25-in.-thick alumi-
num plate (2). The elastic modulus of the wood
is E= 1,700 ksi, and the elastic modulus of the
aluminum plate is E = 10,200 ksi. Determine
the maximum bending stresses produced in
timber (1) and aluminum plate (2).
