Rectangular cross-section and width given the loading state in the figure Bending safety stress of the beam with b = 150 mm 7 em= 10 MPa, Since shear safety stress T em= 600 kPa, In order that the stresses that will occur do not exceed the safety stress values What should be the minimum height h of the beam section. 6 kN/m b -3 m -2 m

How are Engineering stress and strain calculated?

Between  1. Nominal (engineering) stress and true stress and 2. True strain and engineering strain which is always less than the other?

As per mechanical engineer What are the emerging trends and technologies in the field of materials science and engineering that are revolutionizing the design and manufacturing of lightweight and high-strength materials for applications in automotive, aerospace, and other industries, and how do these innovations impact overall product performance and sustainability

Why are pairs of materials more likely to experience thermal stress problems when they represent two different material classes?

List 3 of the design methods that can be applied to avoid the occurrence of fatigue

How are the materials classified as ductile or brittle?

The properties of materials can be classified into the following categories: Mechanical Physical Thermal Electrical Magnetic Describe each category, include two specific properties in the description and say why those properties are of interest to a design engineer.
