17. For a ductile material, toughness is a measure of
(A) Resistance to scratching
(B) Ability to absorb energy up to fracture
(C) Ability to absorb energy till elastic limit
(D) Resistance to indentation
Explanations:- Since, toughness has ability to absorb energy up to fracture.
18. In order to have maximum power from a Pelton turbine, the bucket speed must
be
(A) Equal to the jet speed (B) Equal to half the jet speed
(C) Equal to twice the jet speed (D) Independent of the jet speed
Explanation: Since, velocity of bucket = ½ times the velocity of jet.

through a plane wall with the boundary surfaces ( ) x 0 and x = L = maintained at
temperatures 0ºC and 100ºC. Heat is generated uniformly throughout the wall.
Choose the CORRECT statement.
(A) The direction of heat transfer will be from the surface at 100ºC to surface at
0ºC.
(B) The maximum temperature inside the wall must be greater than 100ºC
(C) The temperature distribution is linear within the wall
(D) The temperature distribution is symmetric about the mid-plane of the wall

## FAQs on Mechanical Engineering (ME) 2013 GATE Paper (Set A) with solution - GATE Past Year Papers for Practice (All Branches)

 1. What is the eligibility criteria for appearing in the GATE exam for Mechanical Engineering?
Ans. To appear in the GATE exam for Mechanical Engineering, candidates must have completed or be in the final year of their Bachelor’s degree in Engineering or Technology. There is no age limit for GATE. However, candidates from countries other than India must have completed or be in the final year of their postgraduate degree in Engineering or Technology.
 2. How can I apply for the GATE exam for Mechanical Engineering?
Ans. To apply for the GATE exam, candidates need to visit the official website of the GATE organizing institute and fill out the online application form. They must provide their personal details, educational qualifications, and upload the required documents. The application fee can be paid online through net banking, debit card, or credit card. After successful submission of the application, candidates will receive an acknowledgment and admit card.
 3. What is the exam pattern for the GATE exam in Mechanical Engineering?
Ans. The GATE exam for Mechanical Engineering consists of multiple-choice questions (MCQs) and numerical answer type (NAT) questions. The total duration of the exam is 3 hours. The paper is divided into three sections - General Aptitude, Engineering Mathematics, and Mechanical Engineering. The General Aptitude section is compulsory for all candidates, while the other two sections are specific to Mechanical Engineering. The exam is conducted online, and the questions are designed to test the candidate's knowledge and problem-solving skills.
 4. How is the GATE exam score calculated for Mechanical Engineering?
Ans. The GATE exam score for Mechanical Engineering is calculated based on the normalized marks obtained by the candidate. The normalization process takes into account the difficulty level of the exam and ensures that all candidates are evaluated fairly. The GATE score is calculated using the formula: S = (M - Mg) / (Mtg - Mg) * (Htg - Hg) + Hg, where S is the normalized score, M is the actual marks obtained by the candidate, Mg is the average marks of all candidates in the same session, Mtg is the average marks of the top 0.1% of the candidates in the same session, Htg is the highest marks obtained by any candidate in the same session, and Hg is the qualifying marks for the general category.
 5. What are the career options for candidates with a GATE qualification in Mechanical Engineering?
Ans. Candidates with a GATE qualification in Mechanical Engineering have various career options. They can pursue higher studies and research in reputed universities or institutes. They can also apply for jobs in public sector undertakings (PSUs) such as BHEL, ONGC, IOCL, etc., which consider GATE scores for recruitment. Additionally, they can opt for jobs in the private sector, work as consultants, or start their own ventures. The GATE qualification opens up opportunities in fields such as design, manufacturing, thermal engineering, automobile engineering, aerospace engineering, and more.
