This paper considers the case of the flat arch and the slightly curved plate, with uniformly distributed load, which may fail not as a result of high stresses and yielding of the material but because of instability, and it is shown how the critical load at which buckling occurs may be calculated. The case of the bimetallic strips used as part of thermostats is also considered.
