What is a zero force member?
Understand the Problem
The question is asking for the definition and explanation of a zero force member in the context of mechanics or structural engineering. Zero force members are members in a structure that do not carry any load under specific conditions.
Answer
A zero force member has no force under a specific load in a truss.
A zero force member is a member in a truss that experiences no force (neither tension nor compression) under a given load.
Answer for screen readers
A zero force member is a member in a truss that experiences no force (neither tension nor compression) under a given load.
More Information
Zero force members provide stability to the truss but do not support any load. They can be identified through certain conditions, such as when a joint connected by two non-collinear members has no external load or reaction.
Tips
A common mistake is assuming a member is a zero force member without carefully considering the joint conditions and loads.
