GATE 2023 Mechanical Paper Questions and Solutions

We are sharing the questions asked in the GATE 2023 Mechanical exam, which will also be helpful for candidates attempting the GATE exam in the coming years. These questions are provided by our students in GATE 2023 Mechanical paper analysis.

Manufacturing and Engineering Materials - Memory Based

Question - In a metal casting process to manufacture parts, both patterns & mould provide shape by dictating where the material should or should not go. Which of the option given correctly describe mould and pattern?

[MSQ]

• Pattern walls indicate boundaries within which the molten part material is allowed, while mould walls indicate boundaries where mould material is not allowed.

• A mould wall indicates boundaries within which the molten part material is allowed, while a patterned wall indicates boundaries where mould material is not allowed.

• Mould can be used to make the pattern

• Patterns can be used to make a mould

Question - Two surfaces, P & Q, are joined together. Which of a given operation, there is no melting of two surfaces P & Q for creating a joint?

• Brazing
• Adhesive Holding
• Spot Welding
• Arc Welding

2. Thermodynamics

Question - A HE extracts (QH) from a TR at T = 1000 k and rejects to (QL) to TR at T = 100k. At the same time, producing (W) work. At the same time, a combination of [QH, QL and W] is allowed.

[MCQ - 1 Mark]
