1) A circular steel bar 50 mm diameter and 200 mm long is welded
perpendicularly to a steel plate to form a cantilever to be loaded with 5 kN at
the free end. Determine the size of the weld, assuming the allowable stress in
the weld as 100 MPa.
2) A plate 100 mm wide and 10 mm thick is to be welded with another plate by
means of transverse welds at the ends. If the plates are subjected to a load of
70 kN, find the size of weld. The permissible tensile stress should not exceed
70 MPa.
3) An eye bolt carries a tensile load of 20 kN. Find the size of the bolt, if the
tensile stress is not to exceed 100 MPa.
4) Find the size of 14 bolts required for a C.I. steam engine cylinder head. The
diameter of the cylinder is 400 mm and the steam pressure is 0.12 N/mm.
Take the permissible tensile stress as 35 MPa.
