Engineering Statics: Open and Interactive

Daniel W. Baker; William Haynes

An open first course in statics, using interactive diagrams to connect forces, moments and equilibrium with engineering problem solving.

Prerequisites

Algebra, trigonometry, vectors and introductory Newtonian mechanics. Basic calculus is useful for distributed loads and geometric properties; no prior engineering statics course is assumed.

Who this book is for

For students beginning the engineering mechanics sequence who benefit from manipulating a diagram as well as reading a worked solution. The book offers a free route into rigid-body equilibrium before dynamics or mechanics of materials. Its interactive approach helps connect the geometry of a force system with the equations used to solve it.

Prerequisites

Algebra, trigonometry, vectors and introductory Newtonian mechanics. Basic calculus is useful for distributed loads and geometric properties; no prior engineering statics course is assumed.

What it covers

The sequence develops force and moment descriptions, equilibrium, structures and geometric properties. Internal loads and section properties prepare for later strength-of-materials work. These ideas provide a systematic way to reduce a physical arrangement to a model with explicit assumptions.

How to use it

Draw an isolated free-body diagram before writing equations. Count the unknown reactions and independent equilibrium relations, then choose axes that simplify the calculation. Change a parameter in an interactive figure and predict the effect before viewing the result. Recheck units, signs and limiting cases, and explain why a mathematically balanced arrangement is or is not physically stable.
