Oct 02, 2017· I have a sledgehammer and deliver a blow of 750 pounds onto a slab of concrete. The concrete breaks apart. The concrete acts 750 pounds of force back on the sledgehammer during impact. Why? I don''t get this. My intuition tells me that since the concrete breaks, it must "reciprocate" a force less than 750 pounds? But the answer is 750 pounds?
Grinding Mill Surging. ... Finally, the amplitude would be expected to depend upon the mill filling, J, since both the restoring force acting on the mill charge and the frictional forces, which depend on the number of contact points, depend upon this quantity. ... for surging to arise in mills grinding cement clinker, limestone or such similar ...
