본문일부 및 목차

▶ 실험목적
집중 하중을 가하였을 때 보가 받는 굽힘모멘트와 처짐량의 관계를 이론적인 계산과 비교하여 이해한다.

부정정보에 대해 이해하고 처짐에 대한 계산과정을 익힌다.

▶ 결과의 개요
양단 고정 지지보와 양단 단순 지지보의 처짐에 대한 실험을 정확성을 위해서 3번의 반복을 했다. 집중하중이 증가함으로써 처짐량도 증가하는 것을 알 수 있었다. 양단 고 정 지지보는 단순 지지보에 비해 처짐량이 작았으며, 오차율도 현저하게 차이가 났다.

양단 고정 지지보의 평균 오차율 : 20.20%
양단 단순 지지보의 평균 오차율 : 67.05%

Ⅰ. 실험목적
재료역학에서 배운 처짐에 대해 이론적인 값과 실제 실험으로 측정한 처짐량을 비교하 기위한 실험이다. 양단 고정 지지보와 양단 단순 지지보에 모멘트와 집중 하중을 가하 였을 경우 얼마나 처지는지 실험해 본다. 또한 처짐량 공식을 유도함으로서 처짐의 정 도와 굽힘 모멘트의 관계식으로부터 이론적인 값을 계산한다. 이를 토대로 실험값과 이론값을 비교해 봄으로써 실험의 오차 정도를 알아보고 그에 대해 생각해 보도록 하 겠다.
