1. The problem statement, all variables and given/known data I meet a problem below: To check if the angle :200x150x12 S275 Grade can take a twist of 30kNm (on plan ) with Span 3m fixed end connected. 2. Relevant equations θ = T L / J G 3. The attempt at a solution My question is that even I got the angle of twist for this member?? how can i check against design twist (30kNm) to see if it is adequate ???
