Unformatted text preview: the pin is to be maintained? b a P P Pin Problem 1.7-8 A ship’s spar is attached at the base of a mast by a pin connection (see figure). The spar is a steel tube of outer diameter d 2 5 80 mm and inner diameter d 1 5 70 mm. The steel pin has diameter d 5 25 mm, and the two plates connecting the spar to the pin have thickness t 5 12 mm. The allowable stresses are as follows: compressive stress in the spar, 70 MPa; shear stress in the pin, 45 MPa; and bearing stress between the pin and the connecting plates, 110 MPa. Determine the allowable compressive force P allow in the spar. Mast Connecting plate Spar P Pin A-PDF Split DEMO : Purchase from www.A-PDF.com to remove the watermark...
