|Step 6||Kindle the imagination on specific product situation to achieve the solution|
Sophistication: Young’s modulus reduces with temperature hence stiffness reduces (axial, bending, shear, torsional) as for isotropic materials.
Native expression: When you heat the metal, it is easy to stretch, bend and twist hence temperature reduces stiffness or increases flexibility.
Sophistication: Stiffer system has higher natural frequency
Native expression: Stiffer component hurries back to original position so takes less time to oscillate to and fro.
Sophistication: Bearing support structure reduces the stiffness of shaft system if the bearing support structure is not rigid.
Native expression: If you support the shaft on hard supports, shaft deflects less but if supported on flexible supports it deflects more.
Sophistication: Gyroscopic effect provides damping unlike physical does not dissipate energy.
Native expression: If no air resistance and no friction in the bearing a fan spins perpetually. Hence any work supplied to overcome the inertia does not dissipate rather is stored as kinetic energy in the fan.
Note: Gyroscopic effect leads to whirling disc consuming of extra energy, thus stiffening the component.
Also, do build facts for inertia.
