Static Bending of Pre-Twisted Cantilever Blading:

摘要: In the present paper static bending of pre-twisted cantilever blading is examined. The linearly about centroid its cross-section to a maximum angle π/2 radians and considered be mounted encastre at root. behaviour such blading, particularly when under distributed load, considerable practical importance.By application variational calculus, equilibrium equations are derived from expressions for total potential energy blades subject either concentrated or uniformly loads. Solution yields deflexions. Over range pre-twist angles between 0 deflexions calculated (1) narrow rectangular subjected method loading, (2) aerofoil load.Sets steel loaded laterall...
