Question 1
A composite beam ıs constructed from a wood beam (75
mm wide, by 150 mm
hıgh) and a
steel plate 75 mm wide The wood and the steel are
securely fastened to act as a
single beam
Calculate the required thickness of the steel plate if the allowable compressıve stress ın
11
the wood is 14 MPa and allowable tensıle stress in the steel plate
is 110 MPa
GIven that the composite beam is subjected
1 2
to a positive bendıng moment M
8.5 kN.m, calculate maximum
bending stress in the wood
Assume that Ew
11 GPa and Eg
= 200 GPa.
