6.2. Hooke’s Law

Question 1

Hooke’s Law

Answer 1

• A spring produces an extension when a load is attached
• According to Hooke’s law, the extension produced is proportional to the applied force (due to the load) as long as the elastic limit is not exceeded.

Question 2

Hooke’s formula

Answer 2

• F = ke
• Where K is the spring constant; force per unit extension

Question 3

Calculating effective spring constants

Answer 3

Series:
1/Ke = 1/k1 + 1/k2

Parallel:
Ke = k1 = k2
