Hysteresis essentially implies the loss of energy in an activity of cyclic nature.Here in case of motion of tire the portion of tread in contact with road surface is under compression due to load of the vehicle and as it moves on it gets extensional deformation. The compressed tread rubber will try to come back to its original state due to its elastic part ...

Cool that you're considering CF, it's a fun material. So first, to answer your questions. If done right it can be fine, but even then it's the least preferable (in my opinion) way to bond FRPs (Fiber Reinforced Plastics). It's hard to do well without special tools, especially in curved and/or hollow profiles, since you need to support the material around ...

This is Work-in-progress How does drilling holes into carbon fibre affect its structural integrity? Drilling holes into carbon fibre has very adverse affects. The main reason is that usually the matrix is some sort of thermosetting resin, and as a result it is relatively brittle. The thing is that the drilling process, will separate fibres from the matrix (...

Restricting the airflow into an air-breathing engine cannot increase its power output. In the case of an internal combustion engine with valves in it, here is the critical fact you are missing: It takes time for the cam system in an engine to push open and then let close the valves in each cylinder. As the engine spins faster and faster, it becomes ...

Could be a method of reducing emissions without modifying the engine, less fuel = less exhaust, albeit with less power as well. An aside, how does reducing valve duration create more low end torque? Unless I'm misinterpreting your question.
