8. Darcy is a welder who has been supplied with diagrams of the rectangular bridge beams that she will make a Pratt truss bridge. Darcy is supplied with a diagram of a beam that is 4 cm deep, 15 cm wide, and 1.4 m long. Darcy is told to make a second beam for another project by enlarging the size of the first beam by a scale of 1:25. What would be the measurements of the second Fuss bridpes are commonly made from steel. beam? b) Darcy is given a scale diagram of the completed truss bridge. Each vertical beam in the scale diagram is 3.5 cm long. If each beam was drawn by reducing the dimensions of the first beam in a), what scale was used?
