Which of the following statements is not correct about beams on elastic supports?
(a) Rotational stiffness has to be considered for journal bearings
(b) Single row bearings can be considered by a node at each bearing location
(c) In wide journal bearing stiffness per unit length has to be considered
(d) Rotational stiffness need not be considered for roller bearings
This question was addressed to me in homework.
My question is from Beams on Elastic Support topic in section Beams and Frames of Finite Element Method
