FAQ
Frequently Asked Questions
No, it is a rare, specialized technical term used primarily in engineering, mechanics, and some sports coaching.
Yes, but it is highly technical and rare (e.g., 'The piston outstrokes'). In most contexts, using a phrase like 'moves outward' is preferable.
The direct opposite is 'instroke' or 'return stroke', referring to the inward or passive movement in a cycle.
Only if they have a technical background (e.g., as a mechanic, engineer, or sports scientist). The average native speaker would likely not know or use it.
