Hello  Engineers, I am planning to take PE mechanical design and preparing for it. In this COVID season, online learning is popular, so I wanted to reach out to other members and see if we can study online? Anyone willing to study on Gmail video chat or other platforms? Please message me. Thanks  ..read more

Hello everyone, I have a question about calculating forces when bending. I want to bend a flat sheet completely round using a cylindrical mandrel and two bending forms. Bending sequence: 1. as you can see in the picture, the force is transmitted from above via the two bending mandrel heels (the force is distributed evenly, 2x Fmin/2, so to speak). 2) In the first step, the sheet is pressed completely into the radius of the lower mold by the bending mandrel. 3 The bending mandrel remains in...

As the Computer Based Testing (CBT) is implemented for all Engineering PE exams starting from April 2020, I would like to initiate a thread to share the experience on Mechanical engineering HVAC & R  and Thermal Fluid Systems (TFS) - PE exam as soon as candidates take the exam and share their experience. Below are some areas of concern, Note: Do not post and disclose any question or part of question here. This is just to share overall experience by not disclosing any details of the...

Hi all, In case you didn't know, every once in a while, NCEES updates the errata sheet for their practice exams, but makes no "official" announcement (that we know of). Check your discipline exam errata in their website The Mechanical TFS and MDM were updated November 22nd, and 23rd, respectively. The HVAC&R errata was last updated 2/8/2021. The previous TFS errata was dated 4-4-2022. Here is what they fixed for this version (we had notified them about all of these corrections... Read more ..read more

The problem solution of calculating BHP does not include sg of acetone. The fluid considered is basically water.  Maybe I am missing certain assumptions pre-made. Please help.  Thanks in advance.  ..read more

Hi all guys I'm new on this forum, and I write this post to ask you for help on a mechanical engineering, hydrodynamic, advanced level problem that I am not able to solve and I hope that some of you certainly better than me can to help. The problem is the following: (I enclose the hydraulic diagram, sorry I know it is not accurate, I did it again on the fly on the PC by copying it from the workbook, unfortunately it is not to scale but it should still be useful to understand the exercise)...

Hello, I'm looking at version 1.5 of the mechanical PE reference handbook. Does anyone know if the thermal conductivity of water is stated anywhere? I have not been able to find it. Also the thermal conductivity of steel. (I did find iron's though ..read more

What happened? Before CBT everyone had a test on the same date and it was very lively posting and interacting as people were in a cohort with that common test date. Then, after the test date came the flood of posts with the post-mortems. I expected some drop of activity when NCEES went to CBT but nothing like this, frankly. Sometimes it can be several WEEKS before someone gets a reply to a post ..read more
