Q2. What is the output of this? static void Main(string[] args) { DivideNumber(233) } static void DivideNumber(int n) { if(n>=10) { DivideNumber(n/10); } Console.Write(n/10) }
Ans. 
The output will be 23323
• The DivideNumber method recursively divides the input number by 10 until it is less than 10

• The Console.Write statement prints the result of n/10 each time the method is called

Q1. GD &T how does it works
Ans. 
GD&T stands for Geometric Dimensioning and Tolerancing, a system used to define and communicate engineering tolerances.
• GD&T uses symbols to specify the allowable variations in form, size, orientation, and location of features on a part.

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

• Examples of GD&T symbols include concentricity, perpendicularity, and position.

• GD&T is commonly used in engineer...read more

Q2. Stress strain and it's graph
Ans. 
Stress strain graph shows the relationship between the force applied to a material and the resulting deformation.
• Stress is the force applied to a material per unit area.

• Strain is the deformation of a material in response to stress.

• The stress-strain graph typically shows a linear elastic region, followed by a plastic region where permanent deformation occurs.

• Materials have different stress-strain curves based on their p...read more

Q1. GD & T symbols and it's uses
Ans. 
GD&T symbols are used in engineering to communicate design specifications and tolerances.
• GD&T symbols are used to specify geometric dimensions and tolerances on engineering drawings.

• They help ensure that parts are manufactured to the correct dimensions and fit together properly.

• Examples of GD&T symbols include concentricity, perpendicularity, and flatness.

• GD&T symbols are often used in conjunction with traditional dime

Q2. Stress strain and it's curve heat treatment process
Ans. 
Stress-strain curve is a graphical representation of the relationship between stress and strain in a material during a mechanical test.
• Stress-strain curve shows how a material deforms under load.

• It consists of elastic, plastic, and fracture regions.

• Heat treatment process involves heating and cooling a material to alter its properties.

• Heat treatment can change the microstructure of a material, affecting its mechanical p...read more
