Welded joint3 Q3. A rectangular cross-section bar is welded to a support by means of fillet welds as shown in Fig., is subjected to an eccentric load of p kN .The maximum bending stress in the bar is 40 MPa. Find the width w and depth d of the bar, if depth is twice that of width. Also determine the size of the welds, if the permissible shear stress in the weld is limited to 25 MPa. 140mm TT d d 2KN W W

A beam is supported and loaded as shown in the figure. Data: L = 1000 mm, c = 300 mm, f = 100 mm, D = 100 mm, d = 80 mm. The beam consists of different parts that are welded, and the fillet weld size a is 4 mm. The load q is 2 kN/m, and P = 10 kN. Calculate the maximum stress in the welds.

A rectangular plate (0 =23°) is formed by welding two triangular plates shown in figure. The plate is subjected to a compressive stress of 2.3 MPa in the x-direction and a tensile stress of 13 MPa in the y-direction. Determine the normal and the shear stresses acting parallel to the weld. Weld Lütfen birini seçin: a. 10.664 MPa/5.50 MPa b. 0.3131 MPa/4.93 MPa c. None d. 0.0358 MPa/5.50 MPa e. 9.3175 MPa/6.09 MPa
