Curved Beam
1)A bolt is subjected to an axial pull of 10KN and transverse shear of 5KN.The yield strength of bolt material is 300Mpa considering F.O.S of 2.5.Determine the diameter of bolt using (i) Maximum normal stress theory(ii) Maximum shear stress theory and (iii) Maximum strain theory(iv)octahedran theory Take poison ratio as 0.25. 2)A Steel bar of 40 mm diameter and 300mm length is subjected to a Torque of 1 KN-m and other two loads are shown in fig.if the ultimate tensile strength and yield strength of bar are 450N/mm2 and 250 N/mm2 respectively. determine the factor of safety using (i)Maximum principle stress theory (ii)Maximum shear stress theory (iii)Maximum strain energy theory All Dimension are in mm 3) .The bracket has a rectangular section whose depth is twice the thickness.Find the cross sectional dimension of bracket if the permissible stress in the material is 50N/mm². Problem on Curved beam 1)The crane hook carries a load of 20KN,as shown in fig,The section is rectangular whose horizontal side is 100mm.find the stress in the inner and outer fiber at a given section. 2)A link of S Shape made of diameter 30mm bar shown in figure determine the maximum tensile stress in the link All Dimension are in mm 3)
