What is the shear plane?
The shear plane is a plane in which shear stress occurs. Like normal voltage, the shear stress is a measure of force per unit of the surface. At any given moment of the structure there are many possible planes that can be defined for stress measurement. Accordingly, according to what the aircraft contains a given area, shear plane. The shear plane is useful for engineers who analyze internal tension in structures.
Stress has the same units as pressure: the force on the surface. Normal voltage results when the folder is inserted into voltage or compression. If the metal rod is stretched vertically, the internal voltage will tend to withstand further deformation. This voltage occurs in the horizontal cross -section of the rod. The voltage is said to be normal because it is directed to the right angle or is normal for horizontal voltages. The shear voltage
is similar to the normal voltage in that it has the same units. However, the direction of voltage is parallel with its stress plane. This drThe extinguishes could result if another set of forces were applied to the same metal bar; Namely, if someone held the bottom of the rod stationary and tried to move the top of the rod to the right. The resulting internal voltage is called shear tension, because parts of the rod try to slip or cut around.
Under these load conditions, the stress on the horizontal plane located in the center of the rod would be directed horizontally. The lower part of the rod would try to move the left; This would expose left -wing forces in the horizontal shear plane. The upper part of the bar would try to move to the right; This would expose the right forces on the same shear plane.
The shear plane analysis is important in preventing mechanical failure of the structure. Each material has a limit of how much stress can last. This limit is the properties of the material itself, rather than the shape of the object. For example, two rubber belts by a canLy be made in different sizes, but of the same material. The larger of them will last more strength before breaking, but only because it has multiple cross -sectional areas for strength distribution; Internal stress will be the same when both sizes fail.
Likewise, the components can break due to too large cut. If the component fails using shear stress, its parts literally slide around. For example, old metal screws normally fail in this way. Limit for editing voltage, as with normal voltage, is a material property.
