Why do cars need to be aerodynamic?

Why do cars need to be aerodynamic? The main concerns of automotive aerodynamics are reducing drag, reducing wind noise, and preventing undesired lift forces at high speeds. For some classes of racing vehicles, it may also be important to produce desirable downwards aerodynamic forces to improve traction and thus cornering abilities. What is the purpose […]

How does plastic deformation occur?

How does plastic deformation occur? Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist. What is the cause of deformation? Deformation is caused by stress, the scientific term for […]
