A mild steel cover plate is to be designed for an inspection hole in the shell of a pressure  vessel. The hole is 120 mm in diameter and the pressure inside the vessel is 6 N/mm2 .  Design the cover plate along with the bolts. Assume allowable tensile stress for mild steel  as 60 MPa and for bolt material as 40 MPa

An eye bolt carries a tensile load of 20kN.Find the size of the bolt(in mm), if the tensile stress is not to exceed100MPa. Draw a neat proportioned figure for the bolt.

Figure 2.1. shows two long plates with same material and equal width w=20 mm that are subjected to a uniaxial tensile load o. One of the plates has a single small central hole with diameter 4mm and another plate has two small holes with a distance of 8mm from each other. The holes are perpendicular to the external tensile load. Develop a computer code (or simulation model) and analyze how stresses will be distributed at the tip of the holes in these two plates for different values of 0. 4mm Figure 2.1. 8mm 4mm

Find the size of 14 bolts required for a CI engine cylinder head. The diameter of the cylinder is 400mm and the steam pressure is 0.12N/mne.Take the permissible tensile stress as 35MPa.
