Q2. Degree of freedom, Pressure
Ans. 
Degree of freedom refers to the number of independent variables that can be changed in a system, while pressure is the force exerted on a surface per unit area.
• Degree of freedom in product design refers to the number of ways a component can move or be adjusted independently.

• Pressure in product design is important for determining the strength and stability of materials and structures.

• Understanding the degree of freedom ...read more

Q1. Beams shear force bending moment
Ans. 
Beams experience shear force and bending moment due to external loads.
• Shear force is the force that acts parallel to the cross-section of the beam, causing it to slide in opposite directions.

• Bending moment is the internal moment that causes a beam to bend.

• Shear force and bending moment diagrams are used to analyze the behavior of beams under different loading conditions.

Q2. Drawing with shear force bending moment
Ans. 
Drawing with shear force bending moment involves plotting the variation of shear force and bending moment along a beam.
• Shear force is the force perpendicular to the beam's axis, causing it to shear or slide.

• Bending moment is the moment that causes a beam to bend.

• Draw shear force and bending moment diagrams to visualize the internal forces and moments in a beam.

• Shear force diagram shows the variation of shear force alon...read more

Q1. Explaining the errors and improvements of engineering drawing
Ans. 
Errors in engineering drawings can lead to misinterpretation and mistakes, while improvements can enhance clarity and accuracy.
• Errors in engineering drawings can include incorrect dimensions, missing views, unclear symbols, and inconsistent labeling.

• Improvements can be made by ensuring all dimensions are clearly labeled, using standardized symbols, providing multiple views for clarity, and maintaining consistency throu...read more

Q1. What is meant by GD&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 correctly and function properly.

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

Q1. What do you know about aircraft
Ans. 
Aircraft are vehicles that are designed to fly through the air, typically powered by engines or propellers.
• Aircraft can be categorized into different types such as airplanes, helicopters, gliders, and drones.

• They rely on aerodynamic principles to generate lift and thrust for flight.

• Modern aircraft are equipped with advanced avionics systems for navigation and communication.

• Commercial aircraft like Boeing 737 and Airbus...read more
