# shearing and bearing stress

The PROBLEM 10 shearing strength of the bolt is 300 MPa ⊙ Bearing stress is the contact pressure between the separate bodies It differs from compressive stress as it is an internal stress caused by compressive forces The bearing stress is the pressure experience by the second surface due to the action Bearing from the first surface (i e Sep 10 2010stress=F/A where F=force of shearing or bearing and A=area of shearing or bearing for a rectanglar beam the shear stress=(3/2)(F/A) for any types of beam shear stress=VQ/Ib where V=shear force Q=first moment of area about the neutral axis I=moment of inertia of the cross section b=width of the beam

## Simple Stresses

Shear stress is developed if the applied force is parallel to the resisting area Example is the bolt that holds the tension rod in its anchor Another condition of shearing is when we twist a bar along its longitudinal axis This type of shearing is called torsion and covered in Chapter 3 Another type of simple stress is the bearing stress

Shearing Stress •Forces P and P'are applied transversely to the member AB A P W ave •The corresponding average shearing stress is •The resultant of the internal shear force distribution is defined as the shear of the section and is equal to the load P •Corresponding internal forces act in

Jan 01 1994According to conventional engineering practice the shear stress i across the key is equal to F the force per unit circumference created by the internal pressure divided by the key width a The nominal bearing stress is equal to F divided by c that portion

Nov 07 2008Shear stress is parallel to the section plane This is harder to describe but an example of this is a screw holding up a small hook in your closet Hang a 2-3 lbs coat on the hook and nothing happens But if you put your bookbag filled with 40-50lbs of books on the hook everything falls to the ground The hook isn't damaged but the screws

bar is compressed the stress are compressive stress the stress acts in the direction perpendicular to the cut surface it is referred as normal stress another type of stress is called shear stress sign convention of the normal stresses are : tensile stress as positive and compressive stress as negative Unit of stress :

Sep 10 2010stress=F/A where F=force of shearing or bearing and A=area of shearing or bearing for a rectanglar beam the shear stress=(3/2)(F/A) for any types of beam shear stress=VQ/Ib where V=shear force Q=first moment of area about the neutral axis I=moment of inertia of the cross section b=width of the beam

9 3 1 Lug Bearing Strength Under Uniform Axial Load The bearing stresses and loads for lug failure involving bearing shear-tearout or hoop tension in the region forward of the net-section in Figure 9-1 are determined from the equations below with an allowable load coefficient (K) determined from Figures 9-2 and 9-3 For values of e/D less than 1 5 lug failures are likely to involve shear

Apr 09 2018Shear Stress and Shear Strain: When a body is subjected to two equal and opposite forces acting tangentially across the resisting section mathematically it is defined as the ratio of tangential force to the cross-sectional area The corresponding strain is known as the shear

## Difference Between Shear Stress and Tensile Stress

Oct 29 2015The shear stress is again defined as the ratio of the force to the area: The definition for tensile stress and shear stress are similar the difference is in the directions of forces For the case on the shown on the diagram the top face of the object gets displaced relative to

Bearing Stress Average normal stress on the contact surfaces of mating surfaces Source: API RP 17G Recommended Practice for Completion/Workover Risers Second Edition July 2006 (Reaffirmed April 2011) Global Standards Bearing Stress A bearing stress is the normal stress on the contact surfaces of mating surfaces

The bearing stress sigma subscript b in the elongated pin hole is distributed uniformly and directed to the left The true distribution of bearing stress in the axial member is somewhat complex therefore an approximate approach is used for design

Dec 04 2007Shear Stress Normal stress is a result of load applied perpendicular to a member Shear stress however results when a load is applied parallel to an area Looking again at figure one it can be seen that both bending and shear stresses will develop Like in bending stress shear stress will vary across the cross sectional area
