Q1. What is angle of projection
Ans. 
Angle of projection is the angle at which an object is projected from the horizontal.
• Angle of projection is measured from the horizontal axis.

• It determines the trajectory of the object being projected.

• A smaller angle of projection results in a shorter range but higher height, while a larger angle results in a longer range but lower height.

• For example, in sports like basketball, the angle of projection of a shot can aff

Q2. Difference between 1st angle,2nd 3rd 4th angle projection
Ans. 
1st, 2nd, 3rd, and 4th angle projections are different methods of representing a 3D object on a 2D plane in engineering drawings.
• 1st angle projection: Commonly used in Europe and Asia, where the object is placed in the first quadrant.

• 2nd angle projection: Commonly used in North America, where the object is placed in the fourth quadrant.

• 3rd angle projection: Commonly used in Australia and the UK, where the object is pla...read more

Q2. What is gd & T, explain the symbols
Ans. 
GD&T stands for Geometric Dimensioning and Tolerancing, a system used to define and communicate engineering tolerances.
• GD&T is a language used to communicate design intent and ensure parts are manufactured to the correct specifications.

• It uses symbols to represent different types of tolerances, such as flatness, perpendicularity, and concentricity.

• Some common symbols include the diameter symbol (⌀), the perpendicularit

Q2. What is the useful use Capacitor in Photo Diode Working?
Ans. 
Capacitor is used to reduce noise and improve the response time of photo diode.
• Capacitor helps in filtering out high-frequency noise from the output signal of photo diode.

• It also helps in improving the response time of the photo diode by reducing the effect of capacitance in the circuit.

• The value of the capacitor used depends on the frequency of the noise and the response time required.

• For example, in a photodetector c...read more
