Exercise : Strength of Materials - Section 7
The springs in cars are used to store strain energy.
In a stress-strain diagram for mild steel, as shown in the below figure, the point A represents
When the retained material is subjected to some superimposed or surcharged load, the total horizontal pressure due to surcharged load is (where p = Intensity of the supercharged load)
The unit of Young's modulus is same as that of stress.
In the below figure, the point B represents upper yield point.
