ESE 2018 GS Paper Solution 21. What is the value of (1525)02 to 2 decimal places? (a) 4.33 (b) 4-36 (c) 4-38 (d) 4-30
ESE 2018 GS Paper Solution In the Laurent expansion of f(z) = (z-1)(2-2) 22. 1 valid in the region 1 1< Iz/ < 2, the coefficient of -t- is (a) 0 (c) 1 (d)-1
ESE 2018 GS Paper Solution x22), what is the value f 23. If u=log , what is the value of x + y. au Ou (a) 0 (b) 1 (c) u (d) eu
ESE 2018 GS Paper Solution 24. What is the residue of the functionea 1 e2z its pole ? z4 at (a) 4 3 4 3 2 3 (d) 2 3
Ans. d) Signage for deep gradients are required not for minor.
Ans. a) Rolling Resistance- C is rolling resistance coefficient W is weight of vehicle. Rolling Resistance= 0.018* 62293.5 N =1121.3 N
ESE 2018 GS Paper Solution 29. For a vehicle travelling at 24 km/hr having a wheel radius of 0-305 m with overall gear ratio G=19.915, and when torque transmitted is 203-6 N.m, the engine speed and power are, nearly 4155 rpm and 88.6 kW (b) 4500 rpm and 88-6 kW (c) 4155 rpm and 95-4 kW (d) 4500 rpm and 95 4 kW (a)
Ans. a) Engine RPM = Overall gear ratio * Wheel rpm = 19.915* Wheel RPM Wheel RPM=Vehicle velocity/Circumference of wheel Putting the values 208.7 rpm will be the value. Engine RPM = 41568 Engine Power= 88.6 kW
Ans. a) Human factors and ergonomics (commonly referred to as HF&E), also known as comfort design, functional design, and systems, is the practice of designing products, systems, or processes to take proper account of the interaction between them and the people who use them Statement 3 is not about ergonomics.
ESE 2018 GS Paper Solution er the following statements with 3 4. Consid reference to Six-Sigma 1. It i s a set of techniques and tools for process improvement. t postulates that any process must not e more than 3-4 defects per one 2. million opportunities. It is an initiative of of the above statements are correct? 1 and 2 only (a) (b) (c) (d) ad 3 only 2 and 3 only 1, 2 and 3
Six Sigma olt uses two disciplined approaches: DMAIC - Used to develop/improve existing practice DMADV - used to devise/design a defect-free procedure
