Mixed Trivia Collection - Badges, Cinema & Aerospace

This is True. Anodizing is indeed an electrolytic passivation process that increases the thickness of the natural oxide layer on metal parts, primarily aluminum. The process enhances corrosion resistance, surface hardness, and allows for dyeing. The anodized layer becomes integral to the metal substrate, not just a coating.

Shot peening is a cold working process where small spherical media bombard the metal surface to create compressive residual stresses. These compressive stresses counteract tensile stresses during service, significantly delaying crack initiation and propagation. This directly improves fatigue strength, which is the ability to withstand cyclic loading. Machinability (A) relates to ease of cutting, ductility (C) to plastic deformation, neither of which are the primary goals of shot peening.

AS9100 is the specific quality management system standard developed for the aerospace industry, building upon ISO 9001. It includes aerospace-specific requirements for quality, safety, and reliability. ISO 6579 (A) relates to microbiology, ISO/TS 16949 (C) is for automotive, and ISO 14000 (D) covers environmental management.

'Kasto maza hai railai ma' from the film 'Parinda' (1989) was picturized at Darjeeling Himalayan Railway, a UNESCO World Heritage Site since 1999. The song was filmed at this location when it was already a UNESCO site. The other songs listed were not filmed at UNESCO heritage sites at their time of picturization.

The Tamil lyric 'arugampul aagirean eppoluthu ennai aaduthaan meivadhu eppoluthu' (meaning 'When will the grass-like swaying stop, when will you embrace me') is from the 2022 film 'Vikram'. The music composer for this film is Vidyasagar, making option C correct. The other composers listed did not work on this specific track.

Passivation is indeed the spontaneous formation of a hard, non-reactive surface film (usually oxide) that inhibits further corrosion. This occurs naturally on metals like aluminum and stainless steel, creating a protective barrier. The statement correctly defines passivation, so 'True' (A) is the correct answer.

Vijay's first film in a lead role was 'Naalaya Theerpu' (1996), directed by his father S.A. Chandrasekhar. While he appeared as a child artist in some films, this was his debut as a lead actor. 'Once More' (A), 'Sendhoorapandi' (B), and 'Kadhalukku Mariyadhai' (C) came after this debut.

Vijay received the Tamil Nadu State Film Award for Best Actor in 1997 for his performance in 'Kadhalukku Mariyadhai' (1997), directed by Fazil. This was early in his career and established him as a promising lead actor. 'Pokkiri', 'Aathi', and 'Sivakasi' are from much later in his filmography.

Vijay made his singing debut in the film 'Rasigan' (1994), where he sang the song 'Chinna Machan'. This marked the beginning of his multiple singing contributions to his own films throughout his career.

Ajith made his acting debut as a lead actor in the Telugu film 'Prema Pusthakam' in 1992, though he gained prominence later in Tamil cinema with successful films like 'Aasai' (1995). His first screen appearance was actually a small role in the Tamil film 'En Veedu En Kanavar' (1990).

7075 is an aluminium alloy with zinc as the primary alloying element (5.1-6.1%), along with magnesium (2.1-2.9%) and copper (1.2-2.0%). It is known for its high strength-to-weight ratio and is commonly used in aircraft structures and other high-stress applications.

Ajith Kumar participated in Formula 3 racing in 2004-2005, competing in the Formula Renault UK and Formula Asia championships. He was a passionate motorsport enthusiast before retiring from racing due to health issues.

The Spinner badge is awarded when a user attempts at least 50% of questions in a quiz and all attempted answers are correct. This indicates perfect accuracy on a substantial portion of the quiz, showing focused mastery rather than attempting every question.

The CHAMP badge is NOT awarded for being the topper of the quiz. It is typically awarded for achieving a perfect score (100%) regardless of ranking, or for other criteria depending on the specific quiz platform's badge system. Being the topper is a different achievement.

The OBSERVER badge is not awarded for commenting on 50% of quizzes taken. Observer badges typically relate to watching, spectating, or viewing without active participation, not commenting activity. The specific criteria depend on the quiz platform's badge design.

The Light Combat Aircraft (LCA) Tejas was designed by the Aeronautical Development Agency (ADA), an agency under the Defence Research and Development Organisation (DRDO) of India. HAL manufactures the aircraft, but the design was done by ADA.

The EARLY BIRD badge is awarded to the first person who takes up the quiz challenge, incentivizing quick participation. It is not based on average time per question, shortest total time, or any speed metric - it's purely about being the first to start.

The song 'Pattu Selai Pol Enna Neeyum Suthi Suthi Kattikadi' was composed by Mani Sharma for the Tamil film. This question tests knowledge of Tamil film music composers and their distinctive work.
