A load indicator comprises a load bearing assembly of first and second load bearing members (23, 22) connected together to bear a lateral load applied to the first member (23), the first load bearing member defining a cavity (25) with the second load bearing member such that it is frangible above an indicator load, and the cavity (25) containing an indicator liquid which escapes from the cavity once the first load bearing member is fractured by said load. The load bearing members (22, 23) comprise cylindrical members arranged concentrically with the outer member (23) having a portion of reduced thickness to render it frangible and to define the cavity (25). The cavity (25) includes an internal volume within the second load bearing member (22). The load indicator may be configured as a load bearing pin to connect two components.
A load indicator comprising a load bearing assembly of first and second load bearing members connected together to bear a lateral load applied to the first member, wherein the first load bearing member defines a cavity with the second load bearing member such that it is frangible above an indicator load, and the cavity contains a flowable indicator which escapes from the cavity once the first load bearing member is fractured by said load,
