Q2. Measurements usage
Ans. 
Measurements are crucial in design engineering for ensuring accuracy and precision in the development process.
• Measurements are used to determine dimensions, tolerances, and material properties of components.

• They help in ensuring that the final product meets the required specifications and standards.

• Various tools such as calipers, micrometers, and gauges are used for taking measurements.

• Measurements also play a key role...read more

Q2. Angke of projection explain
Ans. 
Angle of projection refers to the angle at which an object is projected or launched into the air.
• It is the angle between the horizontal line and the direction in which the object is projected.

• The angle of projection affects the range and height of the projectile.

• For maximum range, the angle of projection should be 45 degrees.

• For maximum height, the angle of projection should be 90 degrees (vertical).

Q4. Modes of heat transfer
Ans. 
Heat transfer occurs through conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between materials (e.g. touching a hot pan)

• Convection: Heat transfer through the movement of fluids or gases (e.g. boiling water)

• Radiation: Heat transfer through electromagnetic waves (e.g. feeling the warmth of the sun)

Q5. Angle of projection
Ans. 
Angle of projection refers to the angle at which an object is launched into the air.
• Angle of projection affects the range and height of the projectile.

• The optimal angle of projection for maximum range is 45 degrees.

• Different angles of projection result in different trajectories of the projectile.

• The angle of projection is measured from the horizontal axis.

Q1. 1st angle 3rd angle drawing difference
Ans. 
1st angle and 3rd angle drawings are two different methods of representing a 3D object on a 2D plane.
• 1st angle projection is commonly used in Europe and Asia, where the object is imagined to be in the first quadrant, while 3rd angle projection is commonly used in North America, where the object is imagined to be in the third quadrant.

• In 1st angle projection, the top view is placed below the front view, while in 3rd ang...read more

Q2. Different symbols of drawing
Ans. 
Different symbols used in engineering drawings represent various elements and features.
• Symbols for dimensions (e.g. diameter, length)

• Symbols for surface finish (e.g. roughness)

• Symbols for welding (e.g. fillet weld)

• Symbols for electrical components (e.g. resistor)

• Symbols for mechanical components (e.g. gear)
