Fer the atate of stress shown on the elemenmt below, Apply the concept of stress transformation to determine OUsing analytical method of transformation equations; (a) The orientation of principal planes and the values of max. and min. principal stresses. Also sketch the principal planes on a rotated stress element along-with the max. and min. principal stresses on the respective planes. (b) The orientation of max. in-plane shear stress and the values of max. and min. in plane shear stresses. Also sketch the max min. in-plane shear stress planes on a rotated stress element labelled with the respective stresses on the planes. (ii) Using graphical method of Mohr's stress eirele technique; find the normal and shear stresses on an inclined plane as shown in the figure below. 43 MP IN MP

Material Properties

Construction in civil engineering demands high strength, durability, and longevity. These targets can be achieved by better design and analysis, along with the correct choice of materials. Different materials have different properties and hence, they respond and performs differently under the various condition of external loadings. It is therefore a critical task of an engineer to select the right material based on the property that the material is supposed to function in real-time. When speaking about the property, there are different categories of material properties like chemical property, physical property, mechanical property, electrical property, magnetic property, thermal property, etc. These material properties form the basis of material selection in various applications.
