Unformatted text preview: 2 ft. center-to-center. The plate is fastened to the ribs using ¼” diameter rivets, d b , which may be considered as pinned supports (not roller supports). The skin is subjected to 300MPH equivalent air pressure acting normal to the plate. The basic wind pressure may be obtained using p=0.00256 v 2 where p=basic wind pressure in pound-force per square foot, v=wind speed in miles per hour. (a) Determine the plate thickness, t.
