Example 8.7 An ISA 200x100×10 angle L03 is welded to a steel plate by means of fillet welds as shown in Fig. 8.17. The angle is subjected to a static force of 150 kN and the permissible shear stress for the weld is 70 N/mm. Determine the lengths of weld at the top and bottom.

Regardless of the design load, the effective length of a 5/8 in. fillet weld that is subjected to stress in a longitudinal direction should not not be less than  A. 2 in. B. 2 1/2 in. C. 3 in. D. 3 1/2 in.

Two steel plates are connected by a pair of splice plates with eight bolts as shown. The ultimate strength of the bolts is bolts is 270 MPa. An axial tension load of P = 480 kN is transmitted by the steel plates. If a factor of safety of 1.6 with respect to failure by fracture is specified, determine the minimum acceptable diameter "d" for the bolts. %3D P. splice plate steel steel plate plate (2) (1)

A fillet-welded joint is shown in the figure. The size of the weld is 8 mm. Safe stress in the weld is 110 N/mm². What is the safe force (to the nearest magnitude) to which the weld can be subjected? 80 mm 60 mm

What is the manufacturing tensional yield strength (lbf) of grade S135 drill pipe? a. This is a trick question because drill pipe size is not provided b. The answer can’t be calculated because the length of the pipe is not given c. The yield strength is 135000 psi and is a property of the steel d. The yield strength is 135000 psi and depends on the cross-sectional area
