Why tensile strength is higher than shear strength?
because of how the molecules are arranged, most materials are a lot stronger in tension than in shear. This is not true for all materials, like chalk or concrete, which are much stronger in shear than in tension.
What is the meaning of steel re bar?
Rebar is an informal term for steel "reinforcing bar". These are steel bars that are placed within the structure before the wet concrete is placed. Steel reinforcement is necessary for almost all structural concrete because concrete has virtually no tensile or shear strength. The rebar provides almost all of the resistance to tension and shear within the structure.
Shear strength of a 8D nail?
75lb
What does stirrup do to reinforced concrete beam?
to resist shear force
Is the characteristic strength of a concrete the same as the compressive strength?
Yes, the characterisrtic strength of a concrete is the same as the compressive strength

Why it is need to use high strength concrete in prestressed concrete?
to offer high resistance in tansion,shear and bond
What are the uses of steel rod reinforcement?
Concrete's best strength rating is in compression, as in equal force from either side. Its weakest rating is in its shear strength, as in force in different areas like snapping a pencil in your hands. To increase concretes shear strength, re-inforcing steel bar is used because of its high shear strength characteristics.

What are the different tests on solid concrete block?
Concrete blocks are tested for Compression and Tensile strength.

Why should one use steel in concrete?
Concrete has high compressive strength needed to sustain the weight of a structure but it has low shear strength (it can be deflected laterally ) and for this reason steel is used which prevents it from getting deflected laterally or buckle .
Why would it be incorrect to refer to shear strength in g or kg?
it would be incorrect to refer to shear strength in g or kg because shear strength is a force not mass
How does shear strength of fine sand effect by void ratio?
Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand. These two features governs the critical state shear strength parameters of the sand. Density, however, dictates the peak shear strength of the sand. i.e. the denser the sand, the higher the peak shear strength. But the critical shear strength remain the same. The denser the sand, the lower the void ratio. Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand.
