Why is fracture stress less than ultimate tensile strength?
Fracture stress is only less than ultimate tensile strength in an engineering stress-strain diagram. This is because the material will experience a maximum stress before it undergoes necking. After necking, stress will decrease again until the material snaps.
What does hoop stress in a material mean?
It is the tangential stress ( normal to the radius) in a circular structure, such as a ring (hoop). For a example if you shrink fit a ring over a cylinder it will have hoop stress, tangential stress along the entire circumference.
What is the difference between Bending STRESS and Direct Stress?
direct stress is a stress normal to the cross section, A, and is the result of an axial load, P. direct stress = P/A Bending stress also acts normal to the cross section but varies from tension on one side and compression on the other. and is the result of a bending moment, M. bending stress = Mc/I where I is the area moment of inertia and c the distance from outer fiber to neutral axis
Relation between tensile stressbending moment and section of modulus?
The relation between bending moment and the second moment of area of the cross-section and the stress at a distance y from the neutral axis is stress=bending moment * y / moment of inertia of the beam cross-section
4 How does the type and direction of stress applied affect the selection of the material and the cross section?

Where will you find the maximum shear stress in a beam?
The maximum stress occurs where shear load is maximum and maximum stress is at the center of the beam cross section if loaded in shear due to bending. It drops to zero at the top and bottom surfaces. The average stress is load divided by area ; maximum stress is dependent on shape of cross section and is 1.5 times load divided by area at the cross section center for rectangular cross section. For shear due to twist, max shear stress in the outer surface.
Why maximum stress concentration factor for plate with a hole is 3?
Maximum stress concentration factor on a plate with a circular hole depends on the radius/size of the circle and the overall width of the plate. So the value can be different then 3
What is the importance of section modulus?
Sectional modulus of any section determines the strength of a section, i.e. if two sections made up of same material then the section with higher section moduls will carry higher load as the allowable stress is constant for a given material. in analysis of it is useful in determining the maximum stress value to which the section is subjected when the moment is konwn from the relation f=(M/Z) where f= stress at extreem fibre M= maximum bending moment on section Z= section modulus = (moment of inertia/ distance of extreem fibre from NA)
Is Modulus of rupture the same as Maximum stress?
Yes.Modulus of RuptureUltimate strength determined in a flexure or torsion test. In a flexure test, modulus of rupture in bending is the maximum fiber stress at failure. In a torsion test, modulus of rupture in torsion is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural strength and torsional strength.
Where in the in cross section minimum shear stress is developed in case of a circular shaft under torsion?
Under torsion only, the shear stress is minimum, in fact zero, at the center point ( where radius is zero)
Why liquid usually transferred in circular pipe?
Circular pipes are easy to fabricate and require the minimum material for a given cross section. If the liquid is under pressure, a circular cross section for the pipe holds the pressure easier and allows the stress to be distributed more or less equally around the perimeter; other cross sections will concentrate the stresses in a few areas around the perimeter.
Why is fracture stress less than ultimate tensile strength?
Fracture stress is only less than ultimate tensile strength in an engineering stress-strain diagram. This is because the material will experience a maximum stress before it undergoes necking. After necking, stress will decrease again until the material snaps.
Is bending stress is directly proportional to section modulus?
The bending stress in a beam is inversely proportional to the section modulus.
Why shear stresses are maximum at neutral axis?
according to bending stress because shear stress at neutral is 0 that is why shear force is maximum
What is breaking stress?
Breaking stress is the maximum amount of stress a material can withstand before it breaks. This is also known as ultimate tensile stress.
What is preconsolidation stress in soil?
Preconsolidation stress is the maximum of vertical overburden stress that a particular soil sample has sustained in the past.
What is compression stress?
In geology the term compression refers to a set of stresses directed toward the center of a rock mass. Compressive strength refers to the maximum compressive stressthat can be applied to a material before failure occurs. When the maximum compressive stress is in a horizontal orientation, thrust faulting can occur, resulting in the shortening and thickening of that portion of the crust. When the maximum compressive stress is vertical, a section of rock will often fail in normal faults, horizontally extending and vertically thinning a given layer of rock. Compressive stresses can also result in folding of rocks. Because of the large magnitudes of lithostatic stress in tectonic plates, tectonic-scale deformation is always subjected to net compressive stress.
