The session begins with a quick comparison between springs in series and springs in parallel, highlighting how force behaves differently in each arrangement. In parallel systems, the total force is shared among the springs, meaning each spring experiences a fraction of the total force. As a result, the system becomes more rigid and less extensible compared to a single spring. Using hooke’s law (F = kx), the lecture shows how the extension of each spring changes when multiple identical springs support the same load. It is demonstrated that while the extension of each spring remains equal, the effective spring constant of the system increases. Students also explore numerical examples and a beam-supported spring problem, where the science behind the changes in the number of springs and applied load require recalculating the combined spring constant and resulting extension. This lecture builds a strong conceptual understanding of how multiple springs behave together and prepares students for more advanced series–parallel spring combinations. 📌 Topics Covered • Review of springs in series vs springs in parallel • Force distribution in parallel spring systems • Extension of identical springs in parallel • Hooke’s Law applied to multiple springs • Combined spring constant: K = nk • Relationship between stiffness and number of springs • Beam supported by multiple springs example • Calculating new extension after removing springs 🎯 Exam Focus • Understanding hooke's law • Applying hooke’s law (F = kx) in multi-spring systems • Understanding force distribution in parallel springs • Calculating effective spring constant K = nk • Determining extension after changes in load or number of springs • Avoiding confusion between series and parallel spring behavior
