The maximum weight in lbs that your bridge can hold with a bridge efficiency of 6000 is; 132.3 lbs
We are given;
Mass of bridge; m = 10g
Bridge efficiency; E = 6000
Now, formula for bridge efficiency is;
E = Maximum load bridge can take/Mass of bridge
Plugging in the relevant values, we have;
6000 = Maximum Load/10
Thus;
Maximum Load = 6000 × 10
Maximum Load = 60000 g = 60 kg
We are told the maximum weight has to be in lbs
Converting kg to lbs is;
1 kg = 2.205 lbs
Thus;
Maximum load = 60 × 2.205
Maximum Load = 132.3 lbs
