This motion can be used to run a lathe or some other machine. 這種旋轉運動(dòng)可用來(lái)開(kāi)動(dòng)車(chē)床或其他機器。
In motions of rotation angular momentum appears in much the same way as linear momentum appears in motion of translation. 在旋轉運動(dòng)中的角動(dòng)量產(chǎn)生的方式與平移運動(dòng)中的線(xiàn)動(dòng)量的產(chǎn)生是基本相似的。
Similar cyclic stresses may have occurred due to wind-induced swaying motion during storage. 同樣在存放時(shí)由風(fēng)力引起的橫向擺動(dòng)也可以產(chǎn)生類(lèi)似的循環(huán)應力。
Impulsion may be recognized by the freely swinging back and the participation of all the joints in the forward motion. 自由擺動(dòng)的背部和身體所有關(guān)節都參與向前的運動(dòng)是動(dòng)力的表現。
