✔ 最佳答案
tensile strength係指物件可以承受既maximum stress既能力~當超過左物件既ultimate tenslie strength
物件會開始更容易被外力拉長 直至去到fracture point 物件斷裂!
hardness就係指果件物件對外力既抗力表現,同物件既彈性(elasticity)有關!
elasticity同分子與分子之間既van der waals' force有關~
elasticity愈大 抗力愈細

tensile strength is a maximum stress of material which can withstand without breaking..
而stress係解applied force per unit area
而stress係解applied force per unit area
