Ice Load Calculation

Calculates a reduced iced-conductor loading case using annular ice area, ice density, wind-on-ice pressure, and span length. The template reports vertical ice weight and combined vector loading for overhead line structural checks.

with-tool: The model is given an executable Python calculator script.

  4. 04

    Task prompt

    The model responds with the declared outputs.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

easy

All inputs given

Distribution line with all values visible

medium

All inputs given

Iced line selected from distribution or transmission cases

hard

Some inputs hidden

Transmission line with ice density embedded in context

Hidden inputs
