Following are some practical and real-life examples of Young's modulus:While walking up or down through the stairway, it is assumed that the young's modulus of the boards are good enough that they resist breaking, when we put our full body weight on them.Springs are used in many mechanical and electronic devices in this modern world. Spring stores elastic energy which handles the load applied to it. Aircraft and racing bicycles use young's modulus of elasticity. In these transport applications, stiffness is required at minimum weight.  When we apply a force on the rubber, then, there are major changes occurring in it. One of them is the 'stretching of rubber'. Due to Young's modulus of elasticity, rubber doesn't break but changes its length and handles the force.The beams used in the bridge are an example of Young's modulus. They play an important role in reducing the stress and the bridge can withstand the huge load of the moving traffic.
