Two wooden planks, each 22 mm thick and 160 mm wide, are joined by the glued mortise joint shown. If the joint fails when the average shear stress in the glue reaches r = 820 kPa, determine the allowable length d of the cuts if the joint is to withstand an axial load of P = 7 kN.
The two steel members are joined together using a 30? scarf weld. Forces of F=15.5 kN are applied at each end, as shown. Determine the average normal stress resisted in the plane of the weld. Determine the average shear stress resisted in the plane of the weld. 220 mm 30P 40 mm
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...
2. A short wooden beam of length L 4 ft is constructed by gluing together two smaller beams to form a single beam of width b 4 in. and height h 8 in. It is simply supported and subjected to a concentrated load P at mid-span as shown. 2.1. If the allowable shear stress in the glue is 300 psi, determine the maximum load P, ignoring self-weight. 2.2.

A wooden beam with rectangular cross-section is supported by means of a pinned joint and a roller as shown. A static force is applied to the beam as shown. Assume that the pin joint and point A are located on the centreline of the beam. If grains of wood in the beam at point A make an angle of 25° with the horizontal as shown, determine the normal and shear stress that act perpendicular and parallel to the grains due...
