Hey all, new member here 1. The problem statement, all variables and given/known data Two uniform 75g marbles 2cm in diameter are stacked on top of each other in a container that is 3cm wide the top marble touches right side of the container, the bottom touches the left side. Point A is the bottom marble left contact point with the container, point B is the bottom marble touch the bottom of the container, point c is the top marble's contact point with the container Attempt at a figure: l top marble, point Cl lmarble contact pointl lpoint A, bottom marble l l_____point B________l What is the force the container exerts at point A,B, and C? What force does each marble exert on each other? 2. Relevant equations Basically since its static equilibrium, , all force and torques add up to zero. Also the equation for Torque, T=sin(phi)*lever arm 3. The attempt at a solution force at B is easy to get since thats just the normal force equal to the combined weight of the two marbles. At A and C, its obvious that they're equal. I can also get the torque due to the top marble on the bottome marble: weight*(.01m)*(sin(30)) after that I don't know what else to do.
