Question 1 Report
Fig. 11 shows four different types of wood joint. The joining method has been selected for its strength and suitability for the materials being used. The joint must be strong enough to withstand the forces applied during use. Different joining methods are suitable for different materials and applications.
The base is wide. It is made in a shop. It is held in place.
The parts are joined with joints. It can be taken apart for storage.
A key advantage of using acrylic here is its natural hardness. It needs to withstand repeated mechanical stress during normal use.

| Joint | Name | Identification |
|---|---|---|
| A | Halving joint / cross halving joint [1] | Two pieces overlap at right angles, each with half of its thickness removed so they sit flush. The diagram shows the horizontal piece housed into a notch cut into the vertical piece. |
| B | Housing joint [1] | A channel (housing) is cut across the full width of one piece, and the end of the second piece sits into it. The dashed lines in the diagram indicate the hidden slot cut into the vertical member. |
| C | Finger joint / comb joint [1] | Interlocking rectangular fingers are cut into the ends of both pieces. The fingers mesh together like interlaced fingers, providing a large glue surface area. |
| D | Butt joint [1] | The simplest joint: the end of one piece is placed squarely against the face or edge of the other with no shaping of either piece. It relies entirely on adhesive or mechanical fixings for strength. |
