Euler–Bernoulli beam theory (also known as engineer's beam theory or classical beam theory) [1] is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics of beams. It covers the case corresponding to small deflections of a beam that is subjected to lateral ...
Macaulay's method (the double integration method) is a technique used in structural analysis to determine the deflection of Euler-Bernoulli beams. Use of Macaulay's technique is very convenient for cases of discontinuous and/or discrete loading.
The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [ 10 ] suspended from each arm (hence the plural name " scales " for a weighing ...
A Roberval balance made by W & T Avery Ltd. in England Detail: the bottom horizontal beam is hidden under the protective cover A Roberval balance shown responding to two masses of equal weight The Roberval balance is a weighing scale presented to the French Academy of Sciences by the French mathematician Gilles Personne de Roberval in 1669.
The reading scale can be enumerated such that the middle beam reads in 100 gram increments, the far beam can read from 0 to 10 grams, and the front beam can read in 10 gram increments. [4] The parts of a triple beam balance are identified as following: [5] Weighing pan - The area in which an object is placed in order to be weighed.
Figure 1: (a) This simple supported beam is shown with a unit load placed a distance x from the left end. Its influence lines for four different functions: (b) the reaction at the left support (denoted A), (c) the reaction at the right support (denoted C), (d) one for shear at a point B along the beam, and (e) one for moment also at point B. Figure 2: The change in Bending Moment in a ...
Typically, the reading scale of the middle beam reads in 100 gram increments, the far beam in 10 gram increments, and the front beam can read from 0 to 10 grams. [2] The triple beam balance can be used to measure mass directly from the objects, find mass by difference for liquid, and measure out substances.
In structural engineering and mechanical engineering, generalised beam theory (GBT) is a one-dimensional theory used to mathematically model how beams bend and twist under various loads. It is a generalization of classical Euler–Bernoulli beam theory that approximates a beam as an assembly of thin-walled plates that are constrained to deform ...
