The search to replace car parts with lighter ones is not limited to any one type of part; according to a spokesman for Ford Motor Company, engineers strive for lightweighting "anywhere we can." [ 7 ] Using lightweight materials such as plastics , high strength steels and aluminium can mean less strain on the engine and better gas mileage as ...
Probability density of stress S (red, top) and resistance R (blue, top), and of equality (m = R - S = 0, black, bottom). Distribution of stress S and strength R: all the (R, S) situations have a probability density (grey level surface). The area where the margin m = R - S is positive is the set of situation where the system is reliable (R > S).
Strength depends upon material properties. The strength of a material depends on its capacity to withstand axial stress, shear stress, bending, and torsion.The strength of a material is measured in force per unit area (newtons per square millimetre or N/mm², or the equivalent megapascals or MPa in the SI system and often pounds per square inch psi in the United States Customary Units system).
The average car weight in 2022 was 4,094 pounds, according to a report from the Environmental Protection Agency. However, what is considered a normal weight will depend on the type of vehicle you ...
Autobesity, also known as car bloat and truck bloat, is the trend, beginning in about the 1990s, [3] of cars increasing in average size and weight. [4] [5] The average weight of cars sold in Europe increased by 21% between 2001 and 2022. [6] In the United States, SUVs and pickup trucks comprised more than 75% of new sales in 2024 compared to 38 ...
Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics , stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other ...
The unsprung mass (colloquially unsprung weight) of a vehicle is the mass of the suspension, wheels or tracks (as applicable), and other components directly connected to them. This contrasts with the sprung mass (or weight) supported by the suspension, which includes the body and other components within or attached to it.
For this reason weight distribution varies with the vehicle's intended usage. For example, a drag car maximizes traction at the rear axle while countering the reactionary pitch-up torque. It generates this counter-torque by placing a small amount of counterweight at a great distance forward of the rear axle.
