* Plastic deformation is defined as a process in which the object due to applied force changes its size or shape in a way that is not
reversible
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.
