This is something I’ve been pondering for sometime and I’m looking to develop a better conceptual understanding so I look forward to any feedback that you can provide. I have attached a drawing for clarity and a text description follows. - Two objects of mass M1 and M2 are on a platform. - Each object has a unique coefficient of friction (between the platform) - The objects are physically connected to one another by a rigid load cell at location 2. - The press moves in the x direction with a sinusoidal profile and it only moves for a -limited distance and it moves very slowly. - The press applies force to M1 through a rigid load cell at location 1. - A horizontal force is applied to M2 through a rigid load cell at location 3. - The force F2 is significantly higher than any resistance imposed by frictional forces. - The press readily moves the blocks and easily overcomes F2, drag, etc.. What I’m interested in discussing is: 1) Since the blocks are under compression are the forces at each of the load cells equal? 2) At one point the press goes against F2 and at another point they work together. How does that impact the relative values of the forces measured by each load cell? Keep in mind the press moves very slowly. So, I’m simply wondering if the compressive forces between the blocks are equal even through the value of the forces vary. Your feedback is greatly appreciated. .
