Help me with Solution, Need fast. Do not waste time. A steel beam is installed in a building when the ambient temperature is -12C. If the beam if fixed at it's ends (prevented from expanding/contracting), calculate the stress that will develop in the beam if the ambient temperature rises to +32C. State whether the stress is tension or compression. Assume E 200,000 MPa and \alpha L = 12x10-6 (/\deg C)

A: Determine the equivalent state of stress on an element at the same point oriented 30° clockwise.

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.
