Q1. What is factor of safety?
Ans. 
Factor of safety is a design parameter that accounts for uncertainties and variations in materials, loads, and other factors to ensure the safety of a structure or component.
• Factor of safety is the ratio of the maximum stress a material can withstand to the maximum stress it is subjected to in a given application.

• It is used to prevent failure due to unexpected conditions such as variations in material properties, manuf...read more

Q2. Stress strain diagram
Ans. 
A stress-strain diagram shows the relationship between stress and strain in a material.
• It typically consists of a linear elastic region, a yield point, and a plastic deformation region.

• The slope of the linear region is the material's Young's Modulus.

• The yield point is where the material begins to deform plastically.

• The ultimate tensile strength is the maximum stress the material can withstand.

• The area under the curve r

Q3. What is GD and T
Ans. 
GD&T stands for Geometric Dimensioning and Tolerancing, a system for defining and communicating engineering tolerances.
• GD&T is a symbolic language used on engineering drawings to specify the allowable variations in form, size, and orientation of features.

• It helps ensure that parts fit together properly and function as intended.

• GD&T uses symbols such as concentricity, flatness, perpendicularity, and position to communic...read more

Q5. What is yield point?
Ans. 
Yield point is the stress at which a material begins to deform plastically.
• Yield point is the point on a stress-strain curve where the material transitions from elastic to plastic deformation.

• It is the stress level at which the material no longer returns to its original shape after the stress is removed.

• Yield point is an important factor in determining the strength and ductility of a material.

• Example: Steel has a well-...read more
