Three boards, each 50 mm thick, are nailed together to form a beam
that is subjected to a 1200-N vertical shear. Knowing that the
allowable shearing force in each nail is 600 N, determine the largest
permissible spactags between the nails.
A beam consists of five planks of 1.5 x 6-in. cross section connected by steel bolts with a longitudinal spacing of 9 in. Knowing that the shear in the beam is vertical and equal to 2000 lb and that the allow-able average shearing stress in each bolt is 7500 psi, determine the smallest permissible bolt diameter that can be used.
