Final answer:
The work required to raise a 200 kg steel beam to a height of 10 meters on the bridge floor is 19,600 joules.
Step-by-step explanation:
The work done to raise the steel beam to a height of 10 meters can be calculated using the formula:
Work = force x distance
Force = weight = mass x gravity
Weight = 200 kg x 9.8 m/s² = 1960 N
Distance = 10 m
Work = 1960 N x 10 m = 19,600 J
Therefore, the work required to raise the steel beam to a height of 10 meters is 19,600 joules.
