3 items that can be weighed by beam balance and 3 by electronic balance
Answers
1. Purchase the required lumber from your local hardware supplier. To build the balance beam you will need six 8 foot (2.44 m) pieces of 1-by-6 pine beams, four 12-inch (61 cm) pieces of 2-by-4 wood planks and four 24-inch (30.5 cm) pieces of 2-by-4 wood planks.
2. Wash the entire surface area of each wood piece. Use soap, water and a washcloth, sponge or coarse brush to scrub the wood pieces thoroughly. This is very important as dirt and grime can prevent the wood glue from working as effectively. Let the wood sit for a while until it is completely dry before adding the glue.
3. Glue the six 8 feet (2.4 m) wood pieces together. Place the pine beams vertically next to one another as that is how they will need to be administered. Glue the largest sides (the flat sides with the most surface area) of the wooden beams together with an industrial-strength wood glue (preferably waterproof). Use a very generous amount of glue in this process as that is what keeps the wood beams together. Make sure they dry before the next step![1]
