What is the crane's capacity at a 42 ft radius if the load chart indicates 25,000 lb at a 40 ft radius and 20,000 lb at a 45 ft radius?

The crane's capacity at a specific radius can often be inferred based on the provided load chart data, which shows capacities at two radii. Since the load capacity typically decreases as the radius increases, we can analyze the values given at the 40 ft and 45 ft radii to estimate the capacity at the 42 ft radius.

At a 40 ft radius, the crane can handle 25,000 lb, and at a 45 ft radius, it can handle 20,000 lb. This indicates that the crane's capacity decreases as the radius increases. The radius of 42 ft is between these two values, and it is reasonable to conclude that the crane's capacity at this radius would fall somewhere between the capacities at the 40 ft and 45 ft radii.

Since the 42 ft radius is closer to the 45 ft radius than to the 40 ft radius, it would be expected that the capacity would be nearer to 20,000 lb, rather than significantly higher towards 25,000 lb. Given the trend observed in the load chart between the two specified radii, the capacity at 42 ft would logically be less than 25,000 lb but more than 20,000 lb.

However,
