A horizontal beam AB with cross-seetional dimensions
4 ft
5 ft-
b#0,75 in.)X KW#8.0 in. is supported by an inclined strut CD and
carries a load P = 2700 lb at joint B (see figure part (a)]. The strut,
which consists of two bars each of thickness 5b/8, is connected to the
beam by a bolt passing through the three bars meeting at joint C
Asee figure part (b)].
OB
3 ft
(a) If the allowable shear stress in the bolt is 13,000 psi, what is the
minimum required diameter d. of the bolt at C?
(b) If the allowable bearing suess in the bolt is 19,000 psi, what is
the minimum required diameter dmin of the bolt at C?
