1. The problem statement, all variables and given/known data Here is a rod of mass m(as shown in figure)which is released from rest.The angle made by the rod with the ground is 600. Assume that the force of friction is enough to prevent sliding of the rod.Find the normal reaction and the frictional force just after the rod is released. http://img138.imageshack.us/img138/1282/xvug.png [Broken] 2. Relevant equations none 3. The attempt at a solution I have calculated the components of the forces on the axis-one along the rod and other perpendicular to the rod.I have used ƩFx=0(as there is no motion in the direction along the rod-if i am correct). But i am not able to compute ƩFy as there is motion in y axis.I am confused please help.
