Defficult to figure out. Why its called virtual? While walking on the earth we push it down. We cant do normal work on it but we use some energy anyway. Now can we say that we do some virtual work on the earth which corresponds to the energy we have used during pushing on the earth.
Very straightforward and simple explanations, helped me a lot to understand how it works, thanks!
Thank you for conveying the concept, I have taken the structural analysis a long time ago, but this sample concept was not explained this simple.
Very simple explanations. Helped me a lot.....
Agree
Needed I a quick basic concept of vitural work. This helped a lot

on what factors we assume the imaginary displacemnet???
Very simple way tell but very speedly speak
Nice explain
how can we assume that this body has done this work??
