Relations between tensile strength ,shear stress and bending stress

babu, look in your class textbook. When you can't understand what that says, look here:

Here are some specific search phrases: "moment of inertia" OR "moment of area" "point loading" "mohr's circle"

Good luck.

That's like asking the correlation between water and pressure.

The relationships are in the statics and dynamics equations. There are many.

Simply put -(it is a hell of a lot more complicated that this) -

Strength is the ability to carry a load, stress is the energy contained in the material from being loaded.

Tensile (ultimate) strength is the level at which the material finally comes apart, as opposed to yield and proprotional strengths, which are the the levels at which material can be loaded without permanent change in shape, or without significant permanent change in shape. What is where, and if they overlay each other, depends on the material itself.

Shear stress is the stress along the line/direction of the load in compression or beam (bending) loading.

Bending stress is several stresses created by a bending moment - most often being considered the compression and tension stresses across the line of the load in a loaded beam.

And if you have to ask for other than idle curiosity, don't go using it - you might kill soembody -especially in hydraulics. Instead, find someone who knows the complicated parts to do it for you.

You need to read more on Strength of Materials before doing a project.For an isotropic material, shear strength = .5773 tensile strength. Bending is tension + compression. So brittle, ductile and composite materials behave quite differently.

Not exactly what you asked for, but maybe what you need:

Here are some relations between Youngs modulus E Rigidity or Torsion modulus n and Bulk modulus k which apply only to a homogeneous, isotropic, substance . The moduli are measured in N/m^2

Given s = Poissons ratio....

n = E / 2(1 + s)

k = E / 3(1 - 2s)

E = 9 n k / (3k + n)

s = (E / 2n ) - 1

Are you talking about all those induced stresses that require tensors? That's too complicated to understand.

Just use schedule 40 pipe stand on the other side of the parking lot when you apply pressure.
