Q 38.
A weld is used for joining an angle section ISA 100 \, \textrm{mm} \, \times 100 \,\textrm{mm} \, \times \, 10 \textrm{mm} to a gusset plate of thickness 15 mm to transmit a tensile load. the permissible stress in the angle is 150 MPa and the permissible shear stress on the section through the throat of the fillet weld is 108 MPa . The location of the centroid of the angle is represented by Cyy in the figure, where Cyy = 28.4mm. The area of cross section of the angle is 1903 mm2 . Assuming the effective throat thickness of the weld to be 0.7 times the given weld size, the lengths L1 and L2 ( rounded-off to the nearest integer ) of the weld required to transmit a load equal to the full strength of the tension member are, respectively
