Springs, of elasticity, widely known as Hooke’s Law, in 1660, which forms the basis of design for many engineering structures and components. He originated the word ‘Cell’ in biology, which describes the tiniest component of a living system. He is the inventor of the iris diaphragm in cameras, the universal

Strain Energy,fect of external load. If the body regains its shape and size, on removed of load, it is said to be within elastic limit. This limit is defined by Hooke’s law which states that within this limit, stress is directly proportional to strain. The internally induced force acting on unit area of the body

Theory of Elastic Failure,yed. The analysis of failure of materials helps to know the actual reasons of their failure. There are five theories relating to a material’s failure, but none of them give the exact reason of failure because of the complexity of compound stress system under multiaxial loading. Yield point is the st

Buckling of Columns,suitable examples of columns. The loaded slender column may deflect laterally and fail by bending (buckling) rather than failing by direct compression. Buckling is one of the major causes of failures in structures. So design of a column is essential to ensure that load carried by it is within the sa

Pressure Vessels,mics and applied mechanics. His greatest contribution to mathematics was the introduction of curvilinear coordinates, and their use in pure and applied mathematics. Lame used his new coordinate system to transform Laplace’s equation into ellipsoidal coordinates to a form where the variables were sep

Unsymmetrical Bending and Shear Centre, plane. Bending takes place about an axis (called neutral axis), which is perpendicular to the plane of symmetry. It is assumed that beams are made of linearly elastic materials, which implies that neutral axis of the beam’s cross-section passes through its centroid.

Fixed Beams,ly indeterminate beam, which involves more than three unknowns and the equilibrium equations of statics alone are not sufficient to determine the support reactions. It involves four unknowns and requires consideration of the deflection of the beam to find the additional unknown.
