The numerical value of this factor is the ratio of the maximum load intensity on the tooth to the load intensity for a uniformly distributed load. Figure 1.3 shows several contact WebUltimate tensile strength is the force per unit area required to break a material under tension. It is expressed in pounds per square inch (psi). The force required to pull apart 1 square inch of plastic may range from 1,000 to 50,000 lbs. or higher. Steel and other structural alloys have much higher tensile strengths, such as SS304 at 84 kpsi.
