1. The problem statement, all variables and given/known data You are working for the Peace Corps in a developing country. Your job is to design a simple, but accurate scale for weighing bulk materials such as food and construction materials. A possible idea consists of a loading platform, D, that is supported by cable AB, where end A is attached to a large tree limb. After loading platform D, weight W3 is applied, which causes point B to move horizontally by a small distance delta that can be measured using a yardstick. Assume: W2 = weight of the loading platform = 50kg W1 = weight of materials being weighed ≤ 250 kg Pulley C is frictionless You are to specify: L = length of cable AB, where L is less than 5m. W3 = weight of the counterweight, where W3 ≤ 20kg. For the specific values of L and W3 you choose, produce a graph with W1 and delta as the vertical and horizontal axes, respectively. Therefore, by measuring the deflection, delta, your graph will tell the user what the weight W1being measured is. 2. Relevant equations Newton's Second Law 3. The attempt at a solution Not a clue how to start, is the system in static equilibrium? If so, then I'd assume to set all the forces at point B = 0. But then I'd have to assign an angle theta that is another variable. I'm so confused.
