| http://www.w3.org/ns/prov#value | - Below is an image that shows how we will test the strength of our bridge design. (The bucket will be larger and we will use sand to add weight.)The bucket will slowly be filled with sand until the bridge flexes 1.5cm or breaks.A scale will be used to weight the pencil, string, bucket, and sand.Your bridge will also be weighed by a scale to determine the weight to strength ratio (efficiency).
