Hooke’s Law | Formula
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 & …

Moment of inertia is the product of first moment of area and the centroidal distance of the area from a given axis. If A.x is the first moment of area of certain section then (Ax).x is …
Continue readingCentroid of I-Section
Centroid of I-section can be found easily with respect to reference x-axis because of section symmetry around y-axis. As shown in the example below; Example Find the centroid of I-section given below. Solution Step: 1 First …
