  1. 9 January 2020 Dear DrD A person trained as a mechanical engineer in the early 1970s rose through the ranks to be Engineering Manager from the mid-1980s and worked for various companies as Engineering Manager. The person had a period where he was not working. He then decided to start working but this time not as an Engineering Manager but as an ordinary mechanical maintenance engineer in manufacturing industry. What problems would such a person have or experience in this new position as an ordinary mechanical maintenance engineer or would he have no problems at all?
  2. 8 January 2020 Dear DrD Here’s an unusual question. A person trained as a mechanical engineer in the early 1970s rose through the ranks to be Engineering Manager from the mid-1980s and worked for various companies as Engineering Manager. The person had a period where he was not working. He then decided to start working but this time not as an Engineering Manager but as an ordinary mechanical maintenance engineer in manufacturing industry.

  3. 15 October 2019 Dear DrD Thank you for responding to my query. Every so often I do come across some strange statements and phrases and “manual side” is one of them. If the boss is a non-mechanical engineer some of the stuff which comes my way I have to seek verification from mechanical engineering experts like you. In industry you come across non-engineers like accountants, sales people, loss control managers and so on and so forth who do not understand what engineering is. I am sure you have come across such people and incidents in your career. Regards ndems
  4. 14 October 2019 Dear DrD If a trainee or apprentice in mechanical engineering (manufacturing industry) starts work today and is helping in cleaning parts and helping in dismantling a machine under the supervision of a qualified mechanical engineer would you say the trainee is “hands on - manual side” or “not hands on - manual side”? Regards ndems
  5. 15 July 2019 Please can someone furnish me with a simple formula for working out the forces generated by the simple machine sketch attached. Some time back DrD referred me to page 382 of your book “Mechanics of Machines”. It is all Greek to me I am afraid. I want to keep it simple. If, say, a very simple machine with two rollers, a metre long each with a diameter of 6 inches (about 152 millimetres) with a drive pulley on one side and a spur gear on the bottom roller and only one spur gear on the other top roller meshing with the gear at the bottom roller. The simple machine
  6. 16 July 2019 Please can someone help me in giving me a formula to wok out the force generated by a simple machine in the sketch attached. Lat time I asked DrD but he referred me to a page in one of his books but I did not understand much. I want to keep it simple. If, say, a very simple machine with two rollers, a metre long each with a diameter of 6 inches (about 152 millimetres) with a drive pulley on one side and a spur gear on the bottom roller and only one spur gear on the other top roller meshing with the gear at the bottom roller. The simple machine is driven by a 3kW elect
  7. 15 July 2019 Second post DrD In my earlier post I used the wrong word - I meant to say "wring water from clothes" not "rinse".
  8. 15 July 2019 Dear DrD In your career as a Professor in Mechanical Engineering you have worked out the force generated by various machines. Some time back I asked you and you referred me to page 382 of your book “Mechanics of Machines”. It is all Greek to me I am afraid. I want to keep it simple. If, say, a very simple machine with two rollers, a metre long each with a diameter of 6 inches (about 152 millimetres) with a drive pulley on one side and a spur gear on the bottom roller and only one spur gear on the other top roller meshing with the gear at the bottom roller.

  9. Hi DrD I hope you are able to see the machine details in the attachment. If not I will send it in a different file format. Envelope - W+D Reel-fed Envelope Machine HELIOS 102 -.htm Envelope Making Machine - W and D.pdf
  10. Please can someone furnish me with the right formula for calculating the Force generated by running manufacturing machinery, in Newtons. This can be any machine like can making machine or envelope making machinery rotating at 350 revolution per minute with 3 kW electric motor.
  11. In Manufacturing industry there are people who fix the machinery and equipment that manufacture a variety of products like cardboard paper, food packing, tin manufacturing machines etc. These people who maintain these machines are called mechanical maintenance engineers. These machines run at very fast speeds (pace) and when they breakdown the mechanical maintenance engineers fix these machines (I am not talking of the breakdown in electrics). Can someone describe the environment as too fast paced for the mechanical maintenance engineer? Because a maintenance engineer only fixes machines w
  12. Hello Forum What are your views on Solicitors or anyone in the legal fraternity assessing/adjudicating mechanical engineering disputes? Can engineering disputes be debated because the building blocks for engineering are Maths and Science where you have single universally right and wrong answers/meanings/solution? How can solicitors be expected to understand engineering they did not study or train in?
