Read full explanation →Correct answer: B
The right pick is option B; brittle ceramics need non-contact material removal — ultrasonic machining suits rectangular holes without fracture MPSC revisits this mechanical/auto fact in later AMVI cycles.
Read full explanation →Correct answer: B
The verified answer here is option B: thin-cylinder longitudinal strain under internal pressure gives δL = PdL/(2tE) when end effects are neglected
Read full explanation →Correct answer: C
The examiner has marked option C, where resilience is the energy-absorbing capacity of a spring material without permanent set Re-read the stem once before finalising — close distractors are common in AMVI papers.
Read full explanation →Correct answer: D
You want option D on this one — machinability of steels improves with sulphur, lead and phosphorus that promote chip breaking and lower cutting forces
Read full explanation →Correct answer: C
Reading the stem carefully, option C fits because extrusion is performed on presses that apply sustained compressive force through a die MPSC revisits this mechanical/auto fact in later AMVI cycles.
