- Q1. What is tolerance and basic tolerance
- Ans.
Tolerance refers to the allowable deviation from a specified dimension in engineering design.
Tolerance is the acceptable range of variation in a dimension or property of a part or product.
Basic tolerance is the general tolerance that is applied to all dimensions unless otherwise specified.
Tolerance helps ensure that parts fit together properly and function as intended.
Examples of tolerance include +/- 0.1mm for a machi...

- Q1. Explain stress, strain curve diagram with example?
- Ans.
Stress-strain curve shows relationship between stress and strain in a material under tension.
Stress-strain curve is a graphical representation of how a material deforms under stress.
It typically consists of a linear elastic region, a yield point, plastic deformation, and ultimate failure.
Example: Steel has a high yield strength, so its stress-strain curve shows a steep initial slope.
Example: Rubber has a low yield stre...
- Q2. What is DOF? How many degrees of freedom from any object
- Ans.
DOF stands for Degrees of Freedom. It refers to the number of independent parameters that define the configuration of an object.
DOF is the number of ways a rigid body can move in 3D space.
For a rigid body in 3D space, there are 6 degrees of freedom - 3 translational and 3 rotational.
Examples of DOF include linear motion along x, y, z axes and rotational motion around x, y, z axes.

- Q1. Explain various GD&T
- Ans.
Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances.
GD&T is used to specify the allowable variations in form, size, and orientation of features on a part.
It uses symbols, such as concentricity, flatness, and perpendicularity, to communicate the desired tolerances.
GD&T helps ensure that parts fit together properly and function as intended.
Examples of GD&T symbo...
- Q2. Explain DFM, DFS, DFA
- Ans.
DFM, DFS, and DFA stand for Design for Manufacturing, Design for Service, and Design for Assembly, respectively.
DFM focuses on designing products that are easy and cost-effective to manufacture.
DFS focuses on designing products that are easy to service and maintain.
DFA focuses on designing products that are easy to assemble.
Consideration of DFM, DFS, and DFA principles can lead to more efficient and cost-effective prod...

- Q1. What is meant by mechanical vibration?
- Ans.
Mechanical vibration refers to the oscillation or movement of an object or structure due to an applied force or disturbance.
Mechanical vibration is the back-and-forth motion of an object or structure.
It occurs when an external force or disturbance is applied to the object.
Vibration can be caused by various factors such as machinery, engines, earthquakes, or even human activities.
It can have both beneficial and detrimen...
- Q2. What is the difference between frequency and the vibration
- Ans.
Frequency is the number of vibrations per unit of time, while vibration is the oscillation or movement back and forth of an object.
Frequency refers to the rate at which an object vibrates or oscillates.
Vibration is the physical movement or oscillation of an object.
Frequency is measured in hertz (Hz), while vibration is measured in amplitude or displacement.
Frequency can be constant or varying, while vibration can have ...
- Q3. What is degree of freedom? They may give you live example and ask you what is degree of freedom of this object
- Q4. What is meant by density? And how you calculate the weight of any object without weighing it directly?
- Ans.
Density is the measure of mass per unit volume. Weight can be calculated using density and volume.
Density is calculated by dividing the mass of an object by its volume.
Weight can be calculated using the formula: weight = density x volume x gravity
Gravity is a constant value of 9.81 m/s^2 on Earth.
For example, the weight of a 1 cubic meter block of iron with a density of 7.87 g/cm^3 would be 77,910 N.
- Q5. What is Pascal's law?
- Ans.
Pascal's law states that pressure applied to a fluid in a confined space is transmitted equally in all directions.
Pascal's law is a fundamental principle in fluid mechanics.
It states that when pressure is applied to a fluid in a closed container, the pressure is transmitted equally in all directions.
This means that if you apply pressure to one part of a fluid, the entire fluid will experience the same increase in press...
- Q6. What do you mean by atmospheric pressure? And how it's very with height
- Ans.
Atmospheric pressure refers to the force exerted by the weight of the air in the Earth's atmosphere.
Atmospheric pressure is the pressure exerted by the weight of the air above a given point on the Earth's surface.
It is caused by the gravitational attraction of the Earth on the air molecules.
At sea level, the average atmospheric pressure is about 1013.25 millibars or 14.7 pounds per square inch (psi).
As you go higher in...
- Q7. You can expect to draw stress and strain curve
