Why can an exact analysis of a structure never be carried out?
Why can an exact analysis of a structure never be carried out?
- Because the loadings and material strengths can only be estimated. (correct)
- Because the structural engineer lacks the ability to model or idealize a structure.
- Because the points of application for the loadings cannot be estimated.
- Because the strength of the materials composing the structure cannot be estimated.
What is the purpose of developing the ability to model or idealize a structure?
What is the purpose of developing the ability to model or idealize a structure?
- To perform a practical force analysis of the members. (correct)
- To make the structure more visually appealing.
- To reduce the cost of fabricating joints.
- To allow for slight rotation in the support connections.
