Suspension bridge main-cable tension

Suspension bridge main-cable tension is the pulling force transmitted along a main cable to support the structure and its loads.

Bar length measures force in newtons. Mass and local gravity determine weight.

A little perspective

The main-cable tension of a suspension bridge is about 2 times 100 meganewtons.

100 meganewtons

Weight: 100 MN; definition.

Weight is gravitational force. An object keeps its mass while its weight changes with local gravity.

Suspension bridge main-cable tension

Defined main-cable tension: 200 MN; defined engineering model; range 100 MN–500 MN.

A defined 200 MN tension in one main cable of a very large suspension bridge. Actual tension varies along the cable and with span geometry, dead load, traffic, wind and temperature.

Defined examples — our methodology

The marked defined main-cable tension is calibrated. Unmeasured illustration details are representative.

Relative size
The main-cable tension of a suspension bridge is about 2 times 100 meganewtons. The main-cable tension of a suspension bridge is approximately 100% greater than 100 meganewtons.

How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • We use 200 MN for the main-cable tension of a suspension bridge; the recorded range is 100 MN–500 MN.
  • The main-cable tension of a suspension bridge: This is an illustrative comparison value, not a claim that every example is the same.
  • The recorded ranges overlap, so the ordering can vary even though the central values differ.

Weight is gravitational force; the same mass weighs differently where gravity changes.
