Hey all, new member here
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?
Basically since its static equilibrium, , all force and torques add up to zero. Also the equation for Torque, T=sin(phi)*lever arm
force at B is easy to get since that's 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.
