Which of the following is the correct equation for stiffness (K) of an element given value of force (F) and displacement (Q)?

(a) FQ=K

(b) KQ=F

(c) KF=Q

(d) KFQ=1

The question was posed to me in an internship interview.

I'd like to ask this question from Beams and Frames in division Beams and Frames of Finite Element Method

The correct choice is (b) KQ=F

To elaborate: The correct equation is given by KQ=F. The value of force (F) is the product of stiffness (K) and displacement (Q). The value of stiffness (K) of the element determines the displacement of the node.
