Question B.1 a) What material properties are often used to determine if a component or structure is capable of carrying its design load adequately and safely when in service ? [2 marks] b) Define what is meant by the term 'factor of safety' in the context of Mechanics and give two examples of typical values for particular structural applications. [2 marks] c) Calculate the maximum load that could be safely supported by an 8mm diameter bolt in both single and double shear if the allowable shear stress of the bolt material is 170 MPa. d) A 15mm diameter steel bar is subject to an axial tensile load of 8 kN in service. If the unloaded length of the bar is 300m E = 200 GPa and = 0.3, calculate : i) ii) iii) the direct stress generated in the material the new length of the bar after application of the load [6 marks] the change in the nominal diameter.
