How do I calculate the Torque produced

The black dots are pivot points and the black square is an air actuator, I want to optimize the CAM, I thought it will be simple i will just Increase the perpendicular distance from the Pivot point and the torque should increase on the cam side, but it didn't, I can wrap my head around how can i solve this analytically, and It is difficult to simulate(the chain over constraints, I can eventually make it work). But there has to be some analytical solution, almost everything does, if you guys have any related data on this please share.
