entical springs, each with stiffness 350 N/m, are connected in parallel (that is, side by side) to hold up a heavy weight. If these springs were replaced by an equivalent single spring, what should be the stiffness of this single spring?

Answer:

Step-by-step explanation:

When two springs of stiffness constant K₁ and K₂ are used in parallel , their equivalent spring constant will be K₁ +K₂

In the present case K₁ = K₂ = 350 N/m

Equivalent K = K₁ +K₂

= 2 X 350

= 700 N/m
