Single shear carries all load on one face whule double shear carries it on two faces, so stress is lowere by a factor of 2 for a given load.
For example shear stress on a cantilever pin is V/A ( load/area, single shear) but on a pin between two supports it is V/2A

∙ 14y agoUnlike joints with fasteners in double shear, those containing fasteners in single shear are nonsymmetrical, which results in local bending of the fastened plates. Thus, even for assemblies loaded in tension, it might be desirable to provide lateral support in the joint region. Therefore, ASTM D 5961 was revised in 2001 to incorporate the laminate bearing lateral support fixture (see Fig. 1). The revised standard still considered only tensile testing of a single- or double-fastener joint and included the option to conduct tests with or without the lateral support fixture. When the fixture was not used, the intent was to simulate an unstabilized joint. When used, it was with the understanding that full stabilization would not be achieved, but rather a condition intermediate between unstabilized single-shear and symmetrical (and thus stable) double-shear loading would be realized.

What is the shear strength of a 1 inch diameter steel shaft?
44,000 psi Steel has a shear strength (in single shear) of 44,000 psi; in double shear of 88,000 psi. The area in shear is the diameter of the shaft times the length of the shaft under stress. If it passes through two 1/4" plates with forces acting in opposite directions the shaft will fail with the application of 22,000 pounds of force. If it passes through three sheets of 1/4" plate (with the force on the center plate opposite the other two) the plate will fail with the application of 23,750 pounds of force (compression {crush} failure).
Define direct shear stress?
Shear force is a load (pounds, or newtons) in plane of the object which produces shear stress ( pounds per sq inch, or Pascals). Shear force is related to shear stress as STRESS = FORCE/AREA
Direct shear test of metal specimen?
what the neccecities of shear test of brass & mild steel
What the symbol of shear?
The mathematical symbol for shear is the greek letter tau - which is similar to the English letter "t". Shear stress is given in Pascals or Megapascals, as this denotes pressure - force over an area - which then leads to the applied shearing load.
Why is graphite low shear strength?
Graphite has low shear strength due to its laminar lattice structure and weak bonding between the layers which allow graphite to slip in layers resulting in low shear strength. - Dr. Aditi Kulshrestha
What is negative shear and Positive shear?
The difference between a positive shear and a negative shear is the direction the image is distorted into
Difference between simple shear strain and pure shear strain of fabric?
no
What is difference between shear and friction?
Shear is a sideways force. Friction is drag - from any direction.
How do you characterized the difference in resistance to shear in fluids?
all fluids have no shear strergths the rate with that they deform will vary with the fluid.
What is negative shear and Positive shear in beams?
The difference between a positive shear and a negative shear is the direction the beam is distorted into. A force that tends to shear the left portion of the beam upward with respect to the right portion is said to produce a positive shearing force.
What is the ratio of average shear stress to maximum shear stress for a circular section?
the average shear stress is 3/4 the maximum shear stress for a circular section
What are the difference kinds stress?
Normal stress and shear stress
What are the purposes of providing shear reinforcement in beam . Explain with suitable sketch?
beams is tying
Explain in detail about the BMdiagram?
The BM diagram can help you in the calculation of the shear force and the bending moment.
How do you calculate the shear load of a nail?
it's fairly simple. The shear strength of the material must be known. Steel is normally 44000 psi in single shear and 88000 psi in double shear. The cross-sectional area of the nail times the shear strength will give you the point of failure of the nail itself, or maximum destructive load. s x a = l Example: an 8d common nail has a diameter of 0.131 inches and a shear strength of 45000 psi the destructive load capacity of the nail in single shear is: 45000 psi x (0.131" x 0.131" x 0.78539) = 606.513 pounds of force. Divide this number by the required factor of safety to get the maximum design capacity for your structure. [ often f.s. = 3, 4, or 5] * cross-sectional area = diameter squared times 1/4 pi note: shear strengths of nails often exceed the crush strength of the material in which they are used.
Is a bolted knife plate connection with timber side plates in double shear?
Yes, it is.
What are difference between a fault zone and a shear zone?
in fault we have a discret breakage, and relatively less deformation. whereas in shear zone we have intense deformation and no disceret breakage.
