Video Description
많은 사람이 자전거를 타는데, 일반적인 자전거는 페달을 뒤로 밟으면 헛바퀴가 돕니다. 그래서 뒤로가고자 할 때는 자전거의 앞머리를 크게 회전시켜야 합니다. 왜 자전거는 후진할 수 없을까요? 뒤로 주행하는 것이 어려워서 그랬을 수 있는데, 어떤 원리로 헛바퀴가 돌게 한 것이고, 왜 페달을 뒤로 밟을 때 독특한 소리가 나는 것인지 알아봤습니다. - 사물궁이 유튜브 채널 구독 : https://youtube.com/@사물궁이 - 사물궁이 시리즈 정주행 : https://youtube.com/playlist?list=PLs8vi5Jd35y55jcjDHMWIXfWjl206sSSF - 궁금증 제보 : https://forms.gle/xT6HQEpVTYbfe9EY8 - 유튜브 멤버십 가입 : https://youtube.com/channel/UC7F6UDq3gykPZHWRhrj_BDw/join - E-Mail : [email protected] ※ 참고자료·논문자료·자문 등 도움 - 자또TV (자문) : https://www.youtube.com/@jinibike - 자전거 동력장치 : https://patents.google.com/patent/KR20010001805A/ko - Secret clutch In your Bike(bicycle)! : https://youtu.be/uB_dQhO1ROI - 자전거 바퀴의 라쳇소리를 바꾸는 방법 : https://youtu.be/Ac9aWfBspRs - Fixed gear bicycle by wikipedia ▪ 배경음악 : Burlesque Heartache – RKVC : After the Soft Rains - South London HiFi : Eyes of Glory - Aakash Gandhi : Gunpowder Tea - Mini Vandals ▪ 애니메이션 감독 : Studio D ▪ 음향효과 : 상업적 목적으로 이용할 수 있는 공정자료 이용 및 자체제작 ▪ 기타 사진·영상 : 상업적 목적으로 이용할 수 있는 사진과 영상 이용 00:00 자문해주신 분 소개 00:06 주제 소개 01:00 자전거가 후진이 안 되는 이유와 독특한 소리가 나는 이유 01:42 후진 가능한 자전거는 없을까? 02:22 후진 가능한 자전거를 안 만드는 이유 #사물궁이 #궁금증 #호기심 #과학 #자전거 #자전거후진 #래칫 #프리휠 #픽시자전거 #픽시자전거후진 Copyright. 사물궁이 잡학지식.
