Q.2. A bar with a rectangular cross-section is weld as shown. Determine the size weld, if the pemissible shear stress in the weld 80 MPa. The rectangle area of a fillet weld is equal to [ 2t (b+/)]. 31KN 160mm

A 1/4 in fillet weld is to transmit a total force of 12,000 lb. If the allowable unit stress in shear on the weld is 15,800 psi, the minimum effective length of the weld must be A. 5.4 B 4.9 in C. 4.3 in D 3.9 in.

Determine the state of stress at point B on the cross section of the post at section a-a given that P = 5.5 kN, F = 3.4 kN. A)Determine the normal stress at point B. B) Determine the shear stress component [(τxz)V]B at point B. C) Determine the shear stress component [(τxy)V]B at point B.

A 40mm thick steel bar that is fabricated by welding two parts together is shown below. Being concerned for the strength of the weld, you need to find the state of stress (normal stress and shear stress) in the plane of the weld for an applied load of 400kN. Draw your result on a stress element. 57° 400 kN 400 kN 100 mm
