Objectives and Topics
The primary objective of this work is to introduce and formalize "Biswas’ trapezium law," a novel mathematical method for calculating the resultant of multiple parallel vectors, expanding upon traditional concepts like the triangle and parallelogram laws.
- Mathematical definition of vector assemblies.
- Characterization of parallel vector sets and their resultant forces.

- Algorithmic determination of resultant vectors in complex multi-vector systems.
Excerpt from the Book
8. Theorem 1: Biswas’ Trapezium law of vectors:
If the joining line of initial points of two parallel vectors and the joining line of shadow points of two terminal points of vectors when the vectors replaced each other on, with the component vectors make a trapezium, then the point of intersection of two diagonals gives the position through which the resultant vector acts, its direction being the same as the direction of the greater vector and the magnitude is equal to the algebraic sum of the component vectors.
Proof: Let U1 and U2 (U1 > U2) be the two parallel vectors acting at the points A and B of a body respectively. In the figures U1 and U2 are expressed as the directed line segments AB and CD respectively.
Summary of Chapters
1. Introduction: The author defines the scope of vector assembly and introduces the discovery of the trapezium law in 1982.
2. Vector assembly: This chapter defines a vector assembly as any collection of vectors and provides symbolic representations for such collections.
3. Initiality , magnitude , direction of a vector: This section details the fundamental properties required to describe a vector within a three-dimensional space.
4. Assembly of parallel vectors: Defines the specific case of assembling parallel vectors and provides examples of such collections.
5. Resultant of vectors: Explains the basic concept of the resultant as the sum of two vectors, referencing standard triangle law applications.
6. Base: Introduces the "base" as the joining line of initial points of multiple vectors acting on a body.
7. Shadow points: Defines the concept of "shadow points" to determine relative positioning of vector terminals.
8. Biswas’ trapezium law of vectors: Presents the central theorem of the work, describing how the intersection of diagonals in a constructed trapezium identifies the resultant vector's point of action.
9. Assembly of single vector: Explains sub-assemblies where an assembly contains only one vector.
10. Step resultant vector: Outlines an iterative process for finding resultants in large assemblies by combining vectors in sequential steps.
11. Final resultant vector: Describes the methodology for arriving at the final resultant in an assembly of R vectors.

Frequently Asked Questions
What is the fundamental purpose of this publication?
The work introduces "Biswas’ trapezium law," a new mathematical approach to calculating the resultant of parallel vectors, serving as an alternative to classical laws.
What are the core thematic fields covered?
The book focuses on vector analysis, specifically vector assembly, parallel vector summation, and the geometric properties of resultant vectors in physical systems.
What is the primary research goal?
The goal is to provide a standardized, step-by-step theorem for summing multiple parallel vectors using geometric constructions known as trapeziums.
Which scientific methods are applied?
The author uses geometric analysis, algebraic summation of vector components, and iterative calculation methods (step resultant vectors) to prove his theorems.
What content is discussed in the main body?
The main body establishes terminology like 'Initiality', 'Base', and 'Shadow points', followed by the formal proof of the trapezium law and iterative algorithms for handling large vector assemblies.
Which keywords best characterize the work?
Key terms include Vector assembly, Biswas’ trapezium law, Resultant vectors, parallel vectors, and step resultant vector.
How does the "Base" function in the context of the trapezium law?
The "Base" acts as the reference line connecting the initial points of vectors, which is essential for constructing the trapezium and locating the point of intersection for the resultant.
What does the "Step resultant vector" approach simplify?
It simplifies the calculation of resultants for very large sets of vectors by breaking the summation into smaller, manageable iterative steps until a final resultant is achieved.
