11:37:33 A KO8 7 . 19% O [Template] A... Mechanical Engineering Department Sant Longowal Institute of Engineering and Technology, Longowal Design of Machine Elements (ME-323) Assignment-2 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.
