Design Verification

We all have seen or used NAIL in our day-to-day life. Technically it comes under the category of a Fastener and is generally used for the following purposes:

  1. Joining of woods by carpenter
  2. Hanging household objects: sometimes it is used to hang pictures, mirrors, and other objects on walls or other surfaces.
  3. it is used to fix roofing materials, such as shingles or tiles, to the roof deck.
  4. Nails are also used to join metal pieces together or to fasten metal to wood or other materials.
  5. Crafting

Let us calculate the load-carrying capacity of a NAIL considering it is used for hanging household objects.

Size of Nail
Load on NAIL

Before proceeding, let’s analyze How can it fails. Here we have assumed that the wall concrete is suitable to withstand the load of the hanging object and the NAIL is completely fixed. it is also considered that the weight is acting at the extreme edge of the NAIL.

Here, failure of NAIL will take place due to bending. the maximum bending moment will be at the point on the nail resting at the wall surface.

W = Maximum weight
