I would be surprised if it wasn't stated in your book. Your attempt is a question, not an attempt. The value of u is the dimensionless ''force' in each member when a unit load of 1 (dimensionless) is applied at the given joint in the direction of the displacement you want to calculate for that joint. You should now make an attempt to understand the given solution.fonseh said:Homework Statement

What is µ ? How to get the value ? It's not stated in my book though
The displacement in a truss refers to the change in position or movement of a specific point in the truss structure. It is typically measured in terms of linear or angular displacement.
The displacement at a point in a truss can be calculated using the principles of statics and structural analysis. It involves determining the forces acting on the truss members and using equations of equilibrium to solve for the displacement at the desired point.
Knowing the displacement at a point in a truss is crucial for ensuring the structural stability and integrity of the entire truss system. It also allows engineers to determine the stress and strain on the truss members, which can help identify potential failure points.
The displacement at a point in a truss can be influenced by various factors such as the magnitude and direction of external forces, the material properties of the truss members, and the geometry and support conditions of the truss.
The displacement at a point in a truss can be controlled by adjusting the design of the truss, such as changing the geometry or material properties, or by adding additional support or reinforcement to the truss members. It is also important to consider the maximum allowable displacement for a given truss in order to ensure its structural stability.
