1. The problem statement, all variables and given/known data Rotor blades attatched to a disc rotate. The rotor blades rotate at a speed of 15574rpm. The blades are 220mm from the centre of the disc. These blades are attatched to a disc that is 400mm in diameter. A force of 8kN/rad acts upon the blades and 600N/rad. (see picture) Calculate the tangential blade loading. Not too sure if centripetal force is the same as tangential force though? 2. Relevant equations (itex)f=mv^2/r(/itex) 3. The attempt at a solution First calculated the centrifugal acceleration (itex)=Mω^2r(/itex) Centrifugal acceleration = 53197m/s Then find the centrifugal force (itex)f=mv^2/r(/itex) I have the velocity and can obtain the mass and radius. I'm not so sure this is the right way to solve the tangential blade loading?? I need to find angular acceleration? Thanks for the in advance help guys.
