A tie bar of width 100 mm and thickness 10 mm is welded to a plate with a longitudinal fillet weld of length 150 mm on each side (total length of weld = 300 mm). Find the strength of the weld if the size of the fillet is 6 mm and the working stress of the fillet weld is 100 MPa.

A steel plate is 30 cm wide and 10 mm thick. If the diameter of the bolt hole is 20 mm, then the net sectional area of the plate is:
