Concept Application 6.2
Knowing that the allowable shearing stress for the timber beam of
Sample Prob. 5.7 is Tall = 0.250 ksi, check that the design is acceptable
from the point of view of the shearing stresses.
Recall from the shear diagram of Sample Prob. 5.7 that
Vmax = 4.50 kips. The actual width of the beam was given as
b = 3.5 in., and the value obtained for its depth was h : 14.55 in.
Using Eq. (6.10) for the maximum shearing stress in a narrow rec-
tangular beam,
=
Tmax
=

3(4.50 kips)
2(3.5 in.) (14.55 in.)
= 0.1325 ksi
Since Tmax < Tall, the design obtained in Sample Prob. 5.7 is
acceptable.
