This is the part you'd do in your book at school. Pick the pieces below, write here or on paper, and photograph anything you draw or work out.
Why the first prototype broke
A team designed a phone stand from 3 mm plywood. The brief said it must hold a 200 g phone at 60° and survive being knocked. The first prototype looked right but snapped at the joint after two knocks.
The team tested again and found the grain of the plywood ran across the narrowest part of the joint, so the wood split along it. They widened the joint from 8 mm to 20 mm, turned the piece so the grain ran along the load, and added a small fillet at the corner to spread the force.
The second prototype survived twenty knocks. It used 15% more material and took four minutes longer to cut — a trade-off the team recorded in their evaluation.
