Answer:
1,042,132 J
Explanation:
The work done can be calculated as Force times distance.
In this case, the force is the weight of the beam, so it is equal to
F = mg = (818 kg)(9.8 m/s²) = 8016.4 N
Then, the distance is 130 m, so the work will be equal to
W = Fd = (8016.4N)(130 m) = 1,042,132 J
Therefore, the answer is:
The work done is 1,042,132 J
