Tensile Strength for a Bolt is determined by applying a Force along it long axis. Shear Strength for a Bolt is determined by applying a Force across its diameter, as it would be loaded in a lug joint. Tensile strength is strength in tension when pulling force is applied. And shear strength is strength against cutting force which is known as shear force.

In a shear joint, there is a (strike/slip) contact surface along which the two sides of the material move in opposite directions, parallel to the joint plane. In a tensile joint, the two sides diverge perpendicular to the joint plane.

The observable consequences of this is that there will be lateral displacement across a shear joint, often with slicken lines/striations; but not in a tensile joint.

Compressive. Pushes inward. Like standing ontop of a can (produces and effect called buckling in this case)

Tensile. Pulls outward - Stretching a rubber band

Shear. Cuts through. - Snaping a piece of chalk using a point load

Bending - Produces a stress which alternates through the thickness of the material. Say bending a ruler. One of the surfaces will be stretching (in tension) the other surface will be in compression. the center of the t.hickness will have neither tension nor compression zero stress due to bending

I guess this is a little easier to explain with diagrams. Hmm sorry for the not so good explanation. Hope its clear.

shear force is maximum at support and zero at centre

Bending moment maximum at centre and zero at support for all simply supported beams..

shear force acts on a place and it induce on a direct place where the loads are transfered..

bending moment act with reference to lever arm distance., (B.M = force X Distance)

unit for shear force is KN

unit for mending moment is Kn.m

The ultimate tensile stress is the failure strength in tension (pull load) while the The ultimate shear stress is the failure strength in shear (as in torsion or direct transverse load . For metals, the shear strength is about 60% of the tension strength.

Stress is a measure of how much force is taken by an object of particular size.

shear stress (symbol tau) is therefore shear force divided by area under shear.

clearly, increasing the force and/or decreasing the size or cross sectional area will result in larger stresses.

shear strain (symbol gamma) is a measure of the deflection caused by a shear stress, and is related via the shear modulus aka modulus of rigidity G, where g = tau /gamma

tensile stress acts along the cross section of the area resulting in increment in the length of the specimen and decreased area of the cross section while shear stress acts along the direction perpendicular to both stresses (eg. tensile & compressive).

A shear stress results from in plane shear loads; a tangential stress applies to a circular shape, such as a hoop, and is a tensile or compressive stress, not shear stress

What is the greatest stress that material can resist before breaking?

The greatest stress that a material can resist before breaking is called the ultimate tensile strength. It is the maximum amount of stress a material can withstand without breaking under tension. Different materials have different ultimate tensile strengths, and it is an important property to consider for designing and engineering structures.

What is the difference between tensile strength and tensile modulus?

Tensile strength is the ultimate capacity of the material to resist a tensile load regardless of deflection.Tensile modulus also known as Young's modulus, is a measure of the stiffness of an isotropic elastic material. It is defined as the ratio of the uniaxial stress over the uniaxial strain. It is determined from the slope of a stress-strain curve traced during tensile tests conducted on a sample of the material.
