Engineering Intro

Radius of gyration of circle is the square root of the moment of inertia of that circular section divided by its area. Mathematically circular radius of gyration can be easily found by using equation; …. …

Radius of Gyration of rectangular solid section is the square root of the moment of inertia of a solid rectangular section to the cross sectional area of that solid rectangular body. Radius of Gyration of …

Percent reduction in area of the geometric shape is the reduction in area as per original area. Mathematically, percentage reduction can be expressed as; [Percentage.Reduction.In.Area=frac{ΔA}{A}times 100]  

Percent elongation is the increase in length of the body per unit orignal length of that body. Mathematically, percentage elongation can be expresses as; ¨ [Percentage.Elongation=frac{Δl}{l}times 100] ..

Mathematically, Bulk Modulus can be represented as; ¨ Bulk Modulus is also known as Bulk modulus of elasticity or Volume modulus.    

Mathematically; Shear modulus can be represented as; ¨ Shear modulus is also known as modulus of elasticity of modulus of rigidity and it is the ratio of shear stress to shear strain.

Hook’s Law Statement: Stress is directly proportional to the strain  until load on material is within its elastic limit. Mathematically, Stress ∞ Strain Stress = A constant x strain Constant is represented by E & …

Direct Strain Direct strain is that produce because of the action of direct stresses. These strains are also named as simple strains. Direct strains are further categorized in to two sub types. Tensile Strain: Compressive …
