    Thermal expansion and Thermal stress: Problem Solving

    San Francisco's Golden Gate Bridge is exposed to temperatures ranging from -15 °C to 40 °C. At its coldest, the main span of the bridge is 1275 m long. Assuming that the bridge is made entirely of steel, what is the change in its length between these temperatures?
    To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55 °C.

    • Laser technology

    Background:

    • Nonlinear atmospheric phenomena challenge high energy laser beam propagation.
    • Existing adaptive optics (AO) models lack atmospheric temporal response considerations, hindering system trade-offs.
    • Accurate modeling is crucial for effective correction of thermal blooming.

    Purpose of the Study:

    • To develop a simplified yet accurate model of the entire AO loop, incorporating atmospheric temporal response.
    • To enable comprehensive AO system trade-off analyses for high energy laser applications.
    • To validate the developed model through experimental verification.

    Main Methods:

    • Development of a novel AO loop model that includes atmospheric temporal dynamics.
