when you consider, the cylinder and t...Dear Arhar,<br /><br />when you consider, the cylinder and the mount as a whole body, then you need not consider internal reaction forces since they cancel out. At the hinge there are in fact two forces, the mount exerts force on the cylinder and the cylinder exerts force on the mount and they are equal and opposite. So when you consider the entire system as a whole these two forces cancel each other.<br /><br />If you draw the free body diagram of the mount only, however, you will see that the hinge exerts a force on the mount. Similarly if you draw a free body diagram of the cylinder , the hinge will be exerting a force on the cylinder in the opposite direction.<br /><br />Hope this helps.Krishna Kant Chintalapudihttps://www.blogger.com/profile/07024636005277277405noreply@blogger.comtag:blogger.com,1999:blog-5997147895880585179.post-21826781375577955812010-11-25T17:49:53.806+05:302010-11-25T17:49:53.806+05:30sir, i have a doubt in prob. 1.260
i think there ...sir, i have a doubt in prob. 1.260<br /><br />i think there is one more force which has not been taken into account. The hinge reaction between the mount and the cylinder is responsible for bringing accelaration to the mount. but this force has not been taken into account while writing the eqns. plz help know if i'm wrong or right. it would help clearing my confusion.arhar jainhttp://arhar.jain@yahoo.comnoreply@blogger.com
