Resultant of Concurrent Forces in Space — Study Resources & PYQs
Determination of resultants for spatial concurrent force systems.
- Estimated study time: 60 minutes
Study resources
- NPTEL Engineering Mechanics - Force Systems I & II (Article) — Lectures 3-4 of the same NPTEL playlist. Explains how to combine concurrent coplanar and spatial forces into a single resultant force.
- Ekeeda Notes - Coplanar Forces: Resultant & Composition of Forces (Article) — Indian engineering-college style notes with solved university exam problems on resultant of concurrent, parallel and non-concurrent coplanar forces.
- Engineering Statics - 2.4 3D Coordinate Systems & Vectors (Article) — Rectangular, spherical and cylindrical description of a force in space, plus direction cosine angles. This is the base for all spatial force problems.
- Engineering Statics - 2.5 Unit Vectors (Article) — How to write a force vector when you only know two points on its line of action - the single most used trick in 3D force problems.
- Engineering Statics - 2.7 Dot Products & 2.8 Cross Products (Article) — Dot product for projections and angles between forces; the cross product page (linked at the bottom) is what you need for 3D moments.
