Are Displacement and Deflection the Same in Beam Analysis?

[EngineeringDave]

Hi I am tackling a question which combines Beam deflection with Bending Virtual Load.
I am wondering whether the displacement found at a point through complementary energy (virtual load) is the same an the deflection through beam integration at that same point?

It maybe a stupid question but I'm struggling to tell the difference!

Sorry just to clarify when I said displacement I mean the transverse displacement (usual symbol is v).

If the two deflections aren't equal, then there is a problem somewhere. You can always analyze a simple problem from a beam table (like a cantilever, for instance) using the two methods to check.
