Understand the forces that shape wagon and road performance, from axle friction to grade resistance, and how to reduce drag.
This edition explains the components of road resistance and how they affect the effort needed to move loads on different surfaces. It offers practical explanations, small‑scale formulas, and historical observations that connect theory to real‑world results.
- Axle friction: how lubrication, surface materials, speed, and temperature change the friction on axles.
- Rolling resistance: factors like wheel diameter, tire width, speed, springs, and road texture that influence effort.
- Impact of wheel size and road surface: why larger wheels can reduce resistance and how road design matters for wear.
- Historical and practical context: what experiments have shown and how they inform modern road planning and vehicle design.
Ideal for readers seeking a clear, practical look at early 20th‑century highway engineering and its enduring lessons for road performance.
