Question

A force of 60 Newtons will compress a spring 0.8 meters. What is the spring constant of the spring?
A. 480 m/Newton
B. 7.5 m/Newton
C. 75 m/Newton
D. 48 m/Newton

Answer 1

Spring force (F) is related to "stretch" (x) by use of a "stiffness constant" (k):

F = kx

60 = k(0.8) -> k = 60 / 0.8 -> k = 75

Answer 2

that's all?

Answer 3

This makes sense because more force is needed to stretch or compress a spring a greater distance.

Answer 4

I thought there would be more though

Answer 5

Yes, This looks harder than it actually is! Funny that way!

Answer 6

heh alright next one coming up :D
