In Structures, we never use Real Work because:

In Structures, we never use Real Work because: Limited to finding D in direction of 1 load at that load point.

In Structures, we never use Real Work because: Limited to finding D in direction of 1 load at that load point. In Structures, Use Virtual Work (VW)

In Structures, we never use Real Work because: Limited to finding D in direction of 1 load at that load point. In Structures, Use Virtual Work (VW) VW = Virtual Force x Real Distance

In Structures, we never use Real Work because: Limited to finding D in direction of 1 load at that load point. In Structures, Use Virtual Work (VW) VW = Virtual Force x Real Distance The Principle of Virtual Work

In Structures, we never use Real Work because: Limited to finding D in direction of 1 load at that load point. In Structures, Use Virtual Work (VW) VW = Virtual Force x Real Distance The Principle of Virtual Work “Virtual Work is Conserved”

In Structures, we never use Real Work because: Limited to finding D in direction of 1 load at that load point. In Structures, Use Virtual Work (VW) VW = Virtual Force x Real Distance The Principle of Virtual Work “Virtual Work is Conserved” Do: Apply Virtual Force (say, 1kip) @ location and direction of desired D.
