Question

Where is the cg of cylinder located?

Answer 1

Description The blue is the mass inside a cylinder. In steady condition, I would want to know where its Center of gravity point shall be from either of the ends. Technically its like one mentioned in figure # 2 .It can be regarded as a portion of cylinder Trials : 1) Divided them as a rectangle and a triangle and tried to combine the CG . (answer did not match with 3D models) Workout : Combined Center of gravity = area of Rectangle*Center of gravity of Rectangle + Area of triangle* Center of gravity of triangle/(Area of Rectangle+ Area of Triangle) In this case, (taking all from left end : CG=(500*50+250*33.33)/(500+250) No clue why it doesn’t match with the 3D modeling software’s answers. Per software, Center of gravity = 41.89 from leftReference https://www.physicsforums.com/threads/center-of-gravity-of-a-portion-of-cylinder.750472/
