According to Wikipedia if the springs connected in series to a block of mass wouldn't be experiencing equal forces then the springs would buckle.What do they mean when it says 'springs would buckle '?Why do they buckle ? How can we understand/accept/feel that springs experience equal forces?
Answer
How can we understand/accept/feel that springs experience equal forces?
- Put a book on a spring on a table. The spring carries the whole weight: Fspring=wbook
- Put a spring on a spring on a table and put a book on top. The top spring carries the weight of the book; the bottom spring carries the weight of the book and the top spring: Fspring,top=wbookFspring,bottom=wbook+wspring,top
Usually you consider springs to have (negligibly) small masses, so wspring,top≈0.
