Mechanical design -- What is the part shown in the drawing?

AI Thread Summary
The discussion centers on understanding the strengths of different types of welds in a mechanical design context, specifically convex, concave, and mitre welds on a lap joint. The key point highlighted is the importance of the effective throat, which influences the weld's strength and stress distribution. Participants suggest that the third type of weld appears stronger at first glance, but further investigation is necessary to grasp the implications of the effective throat. The thread emphasizes the need for proper categorization of schoolwork questions to facilitate learning. The discussion concludes with a reminder to use the appropriate forums for academic inquiries.

New poster has been reminded to post schoolwork-type questions in the HH fourms and to use the Template
Hello guys. In the picture below can u help me with the problems! I cannot understand what exactly should I comment about the strengths. I t would be easier if it was asking about the types of welding :) . Please give some help! Thanks in advance!

They are convex, concave and mitre (or straight) welds on a lap joint.
The most important difference is the effective throat.

This should give you some search terms for your textbooks/lecture notes/Google.
 
Less sharp edges, less stress load. I would say 3rd one is more strong at first glance.

You need to do a bit more investigation as to why the above prior post statement is important.

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
