· In a highstress extraction, that puts high compressive forces on alveolar bone surrounding the tooth, events are initiated that will cause, over a 24 to 96hour period following the extraction, the necrosis of osteoblasts lining the intaglio surface of the socket. The necrosis of the osteoblasts may initiate fibrinolytic activity that lyses any blood clot that may have formed .

A Jaw crusher uses compressive force for breaking of particles the mechanical pressure is achieved by the two jaw of the crusher of which one is fixed while the other moves back and forth relative to it, by a cam or pitman mechanism. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric . What factors affect the .

Two forces are said to be equivalent if they have the same magnitude and direction ( they are equal) and produce the same moment about any point O ( same line of action ). Principle of transmissibility follows from this. Two forces that have the same line of action produce the same external effect ( or rotation) on the body because they have the same net force .

Compressive Forces On Jaw Crusher. A steady compression force is applied by closing the product between the mantle or jaw dies and the crushing chambers wall. Compression crushers such as cones and jaw crushers normally have lower reduction ratios than HSI or VSI crushers but do offer much greater control over the output – as they allow users to define their desired . .

Results: The compressive loading force had a statistically significant influence on the vertical discrepancies (P<.01) (ie, higher forces reduced the vertical discrepancies). When a compressive force of 1 kg was applied to the upper part of the apparatus, the mean vertical discrepancies for G1 (11+/3 microm) and G2 (12+/3 microm) were statistically significantly .

· A single pulse of compressive crushing force, sufficient to break sturdy molluscan shells, ranges from hundreds to thousands of Newtons applied over a period of seconds (Vermeij,1987; Vermeij and Currey,1980). On the other hand, effective peeling requires a fraction of these crushing forces (Preston et al.,1996).

To distribute the compressive forces exerted on the heel during gait, and especially the stance phase when the heel contacts the ground, the sole of the foot is covered by a layer of subcutaneous connective tissue up to 2 cm thick (under the heel). This tissue has a system of pressure chambers that both acts as a shock absorber and stabilises the sole.

The compressive force magnitude increased from to N incrementally as the jaw opened from 10 to 40 mm. Overall data in this study indied that the TMJ tissues undergo low levels of compression at open positions up to 40 mm. Finally, the condition of trismus (increased jaw closing activation with opening) was simulated, the joint reaction force at 20 mm opening .

A Jaw Crusher uses compressive force for breaking material. This mechanical pressure is achieved by the crusher's two jaws dies, one of which is stationary and the other is movable. These two vertical manganese jaw dies create a Vshaped cavity called the crushing chamber, where the top of the crushing chamber is larger than the bottom. Jaw Crushers are sized by .

· Objects placed between the jaws push back with a a resistance force that depends upon a property called stiffness and also the amount of squash you give them. If we consider a fixed amount of squash, say 1mm, then to squash a brick 1mm requires considerably more force than for a sponge. The force equals the stiffness times the squash. Or the stiffness can be .

· If the orthodontic forces are within the accepted therapeutic range, the compressive ischaemic bone necrosis will be insignificant, resorptive remodelling will occur, and controlled tooth movement will follow [1, 13, 46]. On the other hand, if excessive orthodontic forces exceed the adaptive capacity of the affected tissues, the compressive forces may .
