Project 1: Helicopter’s blades are usually modeled as cantilever beams. Your role in a helicopter structures design company is to analyze and design the rotary blade of a helicopter based on cantilever beam theory. Your manager asked you to calculate the magnitude of shear force and bending moment in cantilever for blade modeled as cantilever beam shown in the Figure.1, this task is best achieved by performing the following required steps: 100 kN 50 kN/m I (m) 5 8 10 Figure.3: Helicopter's blade modeled as cantilever beam.

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.
