Determine the diameter of the rod. b.) A solid circular titanium control rod must support an axial tension force of 12,000 lb. Assume that the modulus of elasticity of the titanium in 16,500,000 psi. If the rod must elongate no further than 0.35 in. when the normal stress of the rod is 68,000 psi, determine the minimum rod diameter AND the maximum rod length.

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.

Question

2.) Answer the following:
a.) a 22 ft long solid steel rod is subjected to
a load of 15,000 lb. This load causes the rod
to stretch 0.435 in. The modulus of elasticity
of the steel is 30,000,000 psi. Determine
the diameter of the rod.
b.) A solid circular titanium control rod must
support an axial tension force of 12,000 lb.
Assume that the modulus of elasticity of the
titanium in 16,500,000 psi. If the rod must
elongate no further than 0.35 in. when the
normal stress of the rod is 68,000 psi,
determine the minimum rod diameter AND
the maximum rod length.
