1. A weight is supported by two cables anchored a distance D apart as shown. D A LAB W B LAC C The cable length LÄB is given, but the length LẠC is to be selected. Each cable can support a maximum tension force equal to W. For the weight to remain stationary, the total horizontal force and the total vertical force must each be zero.
