材料力學一 (Mechanics of Materials (1)) from Coursera

課程介紹與教學目標 (About the course)

　　房屋為我們遮風避雨，讓我們安心工作、生活，而結構系統又是房屋的骨幹，讓房屋能站的又高、又直、又穩。你知道橫者為梁，直者為柱，但你知道在結構工程師的眼中，梁與柱有什麼其他的不同嗎？他們其中藏著什麼秘密，能支撐起整個結構？工程師要怎麼決定梁該有多深？柱該有多粗？該用矩形、圓形還是其他形狀？該用實心還是空心？在有地震的地方，設計上是否又有不一樣的考量？

　　材料力學是通往上述問題解答關鍵的一步。在材料力學(一)裡，我們會由大家熟知的虎克定律開始，以蓋房子的重要材料「結構鋼」為例，深入探討「力量」與「變形」這兩個令結構工程師愛恨交加的物理量之間的關係。然後依序探討結構桿件受軸力（拉/壓）、受扭、受彎、受剪四大外力作用下，會在桿件內部產生怎樣的相對應變形與受力，並探討建築結構設計概念與提供桿件設計演算範例。

　　本課程是希望精通「鋼筋混凝土設計」、「鋼結構設計」、「木構造設計」者必備的先修課程，也為對「彈性力學」有興趣者，提供許多基礎知識與這些知識如何實際應用於工程設計。

主要授課對象為土木、建築相關從業人員與在學學生，其他包括工學院各科系同學或對材料力學有興趣的人士，也歡迎選修。

授課形式 (Course format)

　　本堂課將以影片的形式為主, 搭配課後作業及期末報告的形式來進行。
