To prevent this, the load of the clamp should be spread. But spread how? Say I had a 1.5mm thick sheet of steel.
- If I placed it here, would the same thing have happened, but this time the crack would have run along the long side of the steel sheet? Does the fact the width of the steel doesn't go past the front of the clamp make a difference?
- If I moved it forward slightly, I predict it would have prevented damage to the desk. But why? Isn't the load spread amongst the same amount of surface area compared to the above image?
- Would it make a difference if the steel sheet was placed like this? I think the steel sheet would have a sort of lever effect as the centre of gravity is closer to the area covered by the steel sheet load spreader
- Does the tightness of the clamp affect anything? eg loose clamp, exaggerated for effect, the two red dots are where the force is concentrated:
tight clamp, the red lines are where the force is spread:
Or would there still be a concentration of force at the red dots as the monitor moves the centre of gravity and adds a torque effect?
This question is not the same as Mounting a monitor arms clamp on an IKEA desk, what can I use to distribute the load? ; that question asks how, this question is more specific as it asks why.
