Which of the following describes the behaviour of the springs in a series system if a force is applied to cause the system to undergo extension? Consider the case where all springs have the same spring stiffness.

a.

The springs experience different forces

b.

The spring stiffness equivalent is given by Ke=K1+K2+K3...+KnKe=K1+K2+K3...+Kn

c.

The springs experience the same deformations

d.

The spring where the externally applied force experiences the greatest deformation
