Introduction to Statics: Concepts, Principles and Units

Start statics here: its basic models and principles, SI and U.S. units, and a five-step method for solving problems, with practice problems and unit converters.

What Is Mechanics

Learn what mechanics studies, how it splits into statics, dynamics and other branches, and why statics comes first.

Scalars and Vectors in Statics

What makes force a vector, how vectors are drawn and written, and how free, sliding and fixed vectors differ.

Moment and Torque Converter

Convert moments and torques between N·m, N·mm, kN·m, lbf·in, lbf·ft, kip·ft, kgf·m and more, with exact factors and the steps shown.

Resolving a Force into Components Along Two Axes

Split a force into components along any two given directions, and see why oblique components are not projections.
