Homework Statement
Find a3. Assume that the system is placed on a frictionless table.
Assumptions: 45 degree angles and rigid connectors between masses.
Homework Equations
The Attempt at a Solution
So my first thought was just to sum all the forces on mass 1, find the reaction along 1-3 and use that to find a3, is that the correct approach? I.e. the reaction in beam 1-3 divided by the total mass of the system is the solution.
Sum of the forces in x:
mAx = F1 - R13 - R12 Sin45
mAy=R13cos45
were R12 is the reaction along beam 1-2 and R13 is the reaction along beam 1-3. But then I'm stuck, and I'm also not sure I'm approaching this correctly, perhaps I should use T=Iα somehow?
