What is the bridge efficiency when the weight of the bridge is 0.5 lb, the weight of the load added to the bridge before the bridge collapse is 150 lbs and the bridge collapsed additional 10 lbs is added to the bridge.

Answer 1

To calculate the bridge efficiency, we need to use the formula:

Bridge Efficiency = (Weight of the Load / Weight of the Bridge) * 100

In this case, the bridge efficiency would be:

Bridge Efficiency = (150 lbs / 0.5 lb) * 100

Bridge Efficiency = 300 * 100

Bridge Efficiency = 30000%

However, this value is not realistic because the bridge collapsed when an additional 10 lbs was added to it. Therefore, the bridge efficiency is 0%.

Answer 2

What is the bridge efficiency when the weight of the bridge is 0.5 lb, the weight of the load added to the bridge before the bridge collapse is 150 lbs and the bridge collapsed additional 10 lbs is added to the bridge.
