Q3 - A thin-walled cylindrical vessel has an internal diameter of 1m and a thickness of 10 mm subjected to an internal pressure of 2 bar. The vessel surrounded by two semicircular rings tightens by two bolts as shown in the figure below. knowing that the diameter of the bolt is 12 mm and the length of the vessel is 4 m, determine the tensile stress induced in the bolt.

What is Toughness in Mechanics of Material?

The properties of materials can be classified into the following categories: Mechanical Physical Thermal Electrical Magnetic From each category pick one specific property and state its practical application in an engineering context, i.e. pick a product and describe how a particular property of a material relates to the choice of material for that product.

Several applications are listed below. Determine the relative importance of resilience and toughness of the materials chosen for each application. Sort the items based on whethere resilience is most important, toughness is most important, or both are equally important
