Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...
The direction of the subduction system changes since the break-off of slab creates the space, which is the major parameter of this model. [4] The evolution diagram showing how the subduction reversal initiated by a break-off slab at subducting plate: Brown colour is the less dense continental crusts; White colour is the oceanic crust; 1. Two ...
Map of the Panthalassic ocean c. 180 million years ago, showing the position of the Farallon plate. The Farallon plate was an ancient oceanic tectonic plate. It formed one of the three main plates of Panthalassa, alongside the Izanagi plate and the Phoenix plate, which were connected by a triple junction.
In plate tectonics, slab detachment or slab break-off may occur during continent-continent or arc-continent collisions. When the continental margin of the subducting plate reaches the oceanic trench of the subduction zone , the more buoyant continental crust will in normal circumstances experience only a limited amount of subduction into the ...
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.

Cross-section diagram of a thrust fault with a fault-bend fold A thrust fault has the same sense of motion as a reverse fault, but with the dip of the fault plane at less than 45°. [ 22 ] [ 23 ] Thrust faults typically form ramps, flats and fault-bend (hanging wall and footwall) folds.
The first function of a coal breaker is to break coal into pieces and sort these pieces into categories of nearly uniform size, a process known as breaking. [ 1 ] [ 2 ] The second function of a coal breaker is to remove impurities (such as slate or rock), and then grade the coal on the basis of the percent of impurities remaining. [ 2 ]
