GATE Theory of Machines: Cams – Previous Year Questions

4 GATE previous year questions on Cams (Theory of Machines, Mechanical Engineering) with answers and explanations, from every paper.

  1. GATE 2017 ME (ME2) Q42 (2 marks, Numerical answer) – A gear train has gears P, Q, R and S on parallel shafts. Q and R share a shaft. Their tooth counts are 24, 45, 30 and 80 respectively. P rotates at…
  2. GATE 2018 ME (ME2) Q42 (2 marks, Multiple choice) – A cam follower rises by h while the cam rotates through δ radians at constant angular velocity ω. The follower accelerates uniformly for the first…
  3. GATE 2019 ME (ME1) Q15 (1 mark, Multiple choice) – A flat-faced follower is driven by an eccentric circular cam at constant angular speed ω. At t = 0, y(0) = 0 and the system is positioned as shown.…
  4. GATE 2020 ME (ME1) Q48 (2 marks, Numerical answer) – A cam with translating flat-face follower has follower motion y()=4(2-2), 02. Cam-profile radius of curvature must be at least 40 mm everywhere. Find…
