Caravan common sense – a rare commodity?

Caravan common sense – a rare commodity?

Caravan common sense can be fine but used about things technical it’s likely to be based on misleading opinions that contradict the basic laws of physics. Engineering utilises long proven knowledge. This may be (for example) about voltage drop along an electric cable. It may be about the deflection of a spring under load (Hooke’s Law). Or the forces exerted by a caravan yawing or pitching (Newton) etc. All are based on long proven work and often centuries of proven practice.
