Question

You are assigned to inspect metal-composite beam trusses for a new bridge being built over a nearby lake. The manufacturer has run a prototype set of 1,500 beams and conducted strength tests which you consider to be the baseline case, shown by the solid line in all graphs. Examine the graphs, and explain the changes to the baseline curve observed in the dashed line by choosing a cause from the following list. The strength of the beam is shown on the abscissa Click the icon to view the provided graphs Curve Curve D Curve C Curve E Curve A Curve B None of these (b) An impurity, which caused the beams to weaken, was discovered in a sample of 1,500 beams. Choose the correct curve label below Curve B O Curve E O Curve F O Curve C O Curve A O Curve D O None of these mimnmmmmimI immmmImmmIm ImI mIIIIN aselin selin -Baselin

Answer 1

Here curve E is the correct grah here. It is beacuse the the impurity weaken the strength of beams and strength of the beam is shown on abscissa, so it is definite that strength of modified beam shall be less than the baseline beam.

here option E graph is correct.
