Calculation of efficiency


(a) Mass Of Load On Bridge5 Kilogram
(b) Mass Of Bridge0.4 Kilogram
Efficiency12.5




Discussion of the bridge design

1) What is your score on efficiency? If the efficiency is high/low, what went wrong?

Our efficiency is 12.5 and thus it is low. We believe that we did not build our bridge out in a way that the weight will be spread out equally. Our supports was not made properly and thus it broke easily.


2) Which part of the bridge started to give way first? Explain using Physics or Engineering concepts.

The part of the bridge that the weight was put on started to bend. All the weight was concentrated in the middle and the reaction force was not strong enough to oppose the weight.


3) Which part of the bridge provided the most strength in the testing process? Explain using Physics or Engineering concepts.


The arc of the bridge provided the most strength in the testing process. Instead of pushing straight down, the load of an arch bridge is carried outward along the curve of the arch to the supports at each end. The weight is transferred to the supports at either end.
