Analysis and Procedures for Material Selection

The term material selection means to select the right material for various engineering applications. There are various engineering materials available and each has different individual properties. Thorough knowledge of the material properties and behavior is crucial in the design process. For instance, a structural member, such as a beam, is used to support vertical shear loads by the building itself. To withstand such loads, the material of the beam must possess adequate strength and stiffness to resist any deformation that might lead to the formation of cracks.

A flanged bolt coupling is used to connect a solid shaft 110 mm in diameter to a hollow shaft 100 mm in outside diameter and 80 mm in inside diameter. If the allowable shearing stress in the shafts and in the bolts is 58 MPa, how many 16 mm-diameter steel bolts must be used on a 300 mm-diameter bolt circle so that the coupling will be as strong as the weaker shaft? This is an exception to our two decimal rule -- so our answer here must be rounded to the NEXT whole number. Previous Next ENG US
