Homework Statement


Two smooth balls of radius 10[cm] and weight 6[kg] are inside a tube of radius 16[cm] that's on the table. what are the reactions from the walls and what is the minimum mass of the tube to be in equilibrium

Homework Equations


Disassembling of forces using trigonometry

The Attempt at a Solution


The middle triangle is a classic 3-4-5 straight angle triangle multiplied by 15 so the reactions from the walls are 3x15=45. but the reactions are horizontal so at any weight the cylinder stays in place, no?
