scion xb is a structural component designed to resist longitudinal compression  provide outwards-facing support in their lengthwise direction, which can be used to keep two other components separate, performing the opposite function of a tie. They are commonly used in architecture and engineering for instance as components of an automobile chassis , where they can be passive braces to reinforce the chassis and/or body, or active components of the suspension xb           

An automotive suspension  combines the   primary strut function of a shock absorber (as a damper with the ability to support sideways loads not along its axis of compression, somewhat similar to a sliding pillar suspension, thus strut eliminating the need for an upper>suspension arm. This means that a  must have a more rugged design, with  strut

• The MacPherson strut  is a type of car suspension strut   system which uses the axis of a telescopic damper as the upper steering pivot, widely used in   modern vehicles and named after earls macherson who  strut developed the design. Though named for him, it was actually invented by an engineer xb strut named Fornaca at fiat  the mid-1920s. It is possible the MacPherson was inspired by the suspension on the French cottin desgouttes that used the xb strut same design, but with leaf springs. Cottin-Desgouttes xb strut  front suspension xb strut was in turn inspired bywalter chrisies1904 design and he was inspired by plants

Although it is a popular choice xb strut due to its simplicity and xb strut low xb sturt manufacturing cost, the design has a few strutdisadvantages, with regards to the quality of ride it provides and how it affects the handling of the car. Geometric xb strut analysis shows xb strut it cannot allow vertical movement of the wheel without some  xb degree of either camber angle change, sideways movement, or both. It is not generally considered to give as good handling as a double wishbone suspension , because it allows the engineers less freedom to choose camber change and roll center. The wheel tends to lean with the body, leading to under steer. Another drawback is that it tends to transmit noise and vibration from the road directly into the body shell, giving sturt higher noise levels and a "harsh" feeling to the ride compared with double wishbones, xb  requiring manufacturers to add extra noise reduction or cancellation and isolation mechanisms. Also, because of its greater size and robustness and greater xb degree of attachment to the vehicle structure, when the internal seals of the shock absorber portion wear out replacement is expensive compared to replacing a simple shock absorber. However, despite these drawbacks, the strut.
