Concept Question By looking at the potential energy of an element, what can you conclude about the properties required for the basis functions of an euler -bernoulli beam element? They should be differentiable twice 2. The required polynomial order of interpolation is 4 so that we can accomodate non-zero shearing forces at the nodes 3. The slopes at the end nodes of the element shoulc be part of the nodal unknowns and the basis func- tions should be such that continuity of the slope is guaranteed at the element boundaries Statement(1)and 3) all of the above statements 2345 Statement(2 None of the above statements DKDU
