Discuss the most important differences in materials properti

Discuss the most important differences in materials properties (elastic modulus, strength, ductility, density) needed for the following engineering applications:(a) ball bearings, (b) overhead cranes, and (c) aircraft wings.

Solution

ball bearing material should High Compressive Strength ,High Fatigue Strength ,Bearing material should be elastic enough to allow the bearing to return to original shape upon relief of stresses that may cause temporary distortion, such as misalignment and overloading and ductile and less denser.

For overhead crane material should have high strength and ductile denser and high young modulus.

Aircraft wings material should have high elastic modulus also have high strength less density and good ductility.
