Lata leng ni a rawt jat galu kaba wa ai labau
Lata leng ni gaw moi na Miwa mung hte moi na Greece hte Roma mungdan ni hta shawng nnan byin pru wa ai rai nna, dai aten hta masha ni gaw hpun (sh) magri hte galaw ai lata leng ni hpe lang nna hka htung, nbungli jak zawn re ai jak ni hpe mawdaw gau ai.
Middle Ages prat hta, jak hpaji rawt jat wa ai hte maren, masha ni gaw, shingkyit htu ai jak, laika ka ai jak, ahkying aten hte ahkying aten ni zawn re ai jak jak amyu myu hpe hkang na matu, lata leng ni hpe lang hpang wa ma ai.
Hpaga lam rawt malan ai aten hta, Steam engine hte internal combustion engine zawn re ai n-gun nnan ni pru wa ai hte maren, masha ni gaw n-gun jak amyu myu hpe hkang na matu lata hte lang hpang wa ai, ga shadawn, boiler, mawdaw, nbungli, etc.
Dai ni na prat hta, Electronic hte Computer hpaji ni rawt jat wa ai hte maren, masha ni gaw, Television, Computer, CNC jak rai ni zawn re ai Electronic hte CNC jak amyu myu hpe hkang lu na matu, lata hte lang hpang wa sai.
Lata leng hkrang shapraw ai npawt tara
Lata leng ngu ai gaw, n-gun (sh) shara htawt sit ai lam hpe shapraw na matu lever npawt tara hpe jai lang nna, pru wa ai n-gun (sh) shara htawt sit ai lam a galu kaba ai lam hte lam hpe lata leng a radius hte shinggrup ai angle hku nna dawdan ya ai jak rai re. Shaft (sh) spindle hpe hkang ai (sh) gram lajang da ai arung arai ni hte matut nna, hkang ai (sh) gram lajang ai yaw shada lam hpe lu la na matu, shaft (sh) spindle a shinggrup ai lam hpe lata n-gang shinggrup ai hku nna shadut u. Lata leng ni hta, lang ai wa gaw lata leng a masa hte parameter ni hpe hkam la lu na matu, shinggrup lu na matu, hti lu na matu, lata n-gang, shadawn shadang, masat kumla ni zawn re ai karum shingtau ai arung arai ni hpe bang da ai.
Htap htuk ai lata leng ni hpe hkrang shapraw nna, laksan galaw ai shaloi, lawu na masa ni hpe madung hku nna myit yu ra ai:
