[QUOTE="Karol, post: 4993895, member: 20512"] [h2]Homework Statement [/h2] 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 [h2]Homework Equations[/h2] Disassembling of forces using trigonometry [h2]The Attempt at a Solution[/h2] 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?
