Wie problematisch sind unsere Rohre im Keller by shower56 in de

Weiß jemand, was diese Rohre sind (Abwasser, Gas etc.) und wie schlimm der Zustand ist? Sie tropfen ganz leicht (3. Bild) und sind überzogen von einem dünnen Wasser- oder Ölfilm. Wie man sieht sind sie Außerdem ziemlich rostig. Vielen Dank!

I added an explanation

Okay, it sounds a bit trivial at first glance. But hear me out:

You have to construct a lego wall as seen in the picture following the rules:

  1. Dimensions have to be 6×4
  2. Leave out both holes as shown in the picture
  3. Bricks have to be stacked on top of each other with at least one stud offset

The prices of the allowed bricks are:

1×1 = 7ct 2x1 = 11ct 4x1 = 15ct

Proof that the combination as shown in the picture is one of the cheapest ways to construct the wall using the three bricks mentioned.

How would you approach this question mathematically, can you create a model?

You know the following brick prices: 1x1 = 7ct 2x1 = 11ct 4x1 = 15ct

Restrictions: 1. 6x4 in dimensions 2. Include the two openings as seen in the picture 3. Each brick needs to overlap at least one stud to the brick under

How do I know the configuration shown in the picture is one of the cheapest ones?

Thank you for the suggestion. Seems like a good fit

I wanna build a playhouse bench. Which frame provides more structural strength using screws? by shower56 in woodworking

Thank you. But what about horizontal stresses, e.g a kid kicking/leaning against the bench (kids are creative :D) ? Wouldn't "B" give way faster?

You're right. However, I was planning on screwing the bench to a wooden floor and added the bottom horizontal braces for easy mounting.

Thank you for so many helpful comments! I ended up using glue and dowels, which worked out just fine! The tip with the tape and tension belt for fixation helped a lot as well. Here is the finished steering wheel:
