Intro to Springs (Hooke's Law) Video Lessons

Concept

# Problem: a) Two springs with spring constants k1 and k2 are connected in parallel. What is the effective spring constant keff? In other words, if the mass is displaced by x, find the keff for which the force equals F= -(keff)x.

###### FREE Expert Solution

Hooke's law:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{-}}{\mathbf{k}}{\mathbf{x}}}$

(a)

The two springs have the same extension, x.

F1 = -k1x

F2 = -k2x

F = -keqx
