Question

Quizplus · Accepted Answer

Pushrods are typically made of steel, whereas pushtubes can be made from lightweight materials like carbon fiber, resulting in high strength with less weight. This can provide advantages in aircraft and other weight-sensitive applications. While pushtubes also have the potential to be stronger than pushrods, this isn't always necessary, and may not be a significant advantage. Cheaper materials may also be an advantage in some applications, but this isn't a guaranteed benefit of pushtubes. The advantage of working better with short rod lengths isn't a factor in comparison between pushrods and pushtubes, as both can be designed to work effectively with short lengths.
