: In an effort to increase the miles per gallon in automobiles many steel parts are being replaced with polymer parts where the strength of steel is not required.
The blades of the fan that cool the radiator experience a centripetal stress of less than 1×105 Pa when the fan blade material density is reduced to approximately 1×103 kg/m3. Vibration of the fan blades is the greatest problem, and vibration amplitude is minimized by maximizing the elastic modulus (stiffness) of the blade material. In addition it is determined that the Izod impact strength must be a minimum of 100 for sufficient resistance to fracture and fatigue. To control cost it is necessary to select a commodity polymer. Polymers with glass or other material reinforcement are too expensive for this design. What material discussed in this chapter would best suit the design requirements?
Jupiter's Great Red Spot is a low-pressure storm, like a hurricane on Earth
