Stress-strain graph of stainless steel shows high strength and ductility.

• Stainless steel has a linear elastic region followed by a yield point and then strain hardening.

• The ultimate tensile strength of stainless steel is higher than mild steel.

• Stainless steel exhibits a significant amount of plastic deformation before failure.

• The area under the stress-strain curve represents the energy absorbed by the material during deformation.

Design parameters are the specific requirements that an equipment must meet to function effectively.

• Design parameters include factors such as size, weight, power consumption, and operating temperature.

• Other important parameters may include durability, reliability, and ease of maintenance.

• For example, when designing a car engine, parameters such as horsepower, torque, and fuel efficiency must be considered.

• Similarly, when designing a medical device, parameters such as accuracy...read more

Explanation of bending moment diagram

• Bending moment diagram is a graphical representation of the variation of bending moment along the length of a beam

• It is used to determine the maximum bending moment and the location of the maximum bending moment in a beam

• The area under the bending moment diagram represents the shear force acting on the beam

• The bending moment at any point on the beam can be calculated by taking the algebraic sum of the moments to the left or right of that p...read more

Understanding basic strength of materials formula, material properties, and pump operation is essential for a design engineer.

• Strength of materials formula includes stress, strain, and modulus of elasticity

• Material properties include density, thermal conductivity, and coefficient of thermal expansion

• Pump operation involves understanding flow rate, head, and efficiency
