 Posted by: john2005 ® 04/14/2005, 10:04:58 Author Profile Mail author Edit Hi, I have a force calculation problem. I have a ring with a ID of 20inch and OD of 21.25 inch. It is a two piece ring for mounting it on a shaft with 20 inch Dia with two 5/16 -20 bolts. If the shaft is spinning with an RPM of 4100 I need to calculate the Centrifugal force caused by the ring acting on the bolts holding the ring on the shaft. PLease can anyone help me with this.Thanks
