Three plates are joined with a 12 mm diameter pin as shown. Determine the maximum load P that can be transmitted by the joint if:(a)The maximum normal stress on a cross-section of the plates at the pin must not exceed 372 MPa.(b)The maximum bearing stress between a plate and the pin must not exceed 612 MPa.(c)The maximum shear stress on a cross-section of the pin must not exceed 268 MPa.(d)The punching shear resistance of the material in the top and bottom plates is 303 MPa.

A W410 × 60 steel beam (see Appendix B) is simply supported at its ends and carries a concentrated load of P = 300 kN at the center of a 6.0-m span. The W410 × 60 shape will be strengthened by adding two cover plates of width b = 250 mm and thickness t = 16 mm to its flanges, as shown. Each cover plate is attached to its flange by pairs of bolts spaced at intervals of s =...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
