Multiple Choice

In post-tensioned concrete cables, the greased strand is seven-strand and the wire diameter is half-inch; the tensile force is about 25,000 lbs.

The key idea here is that the force carried by a post-tensioned strand is the load it is stressed to during installation. In this scenario, the strand is a seven-wire, 1/2-inch-diameter greased strand, and the problem explicitly states the tensile force is about 25,000 pounds. That value is the actual tension the strand is designed to carry, regardless of the strand’s size or configuration. So the best match is the about 25,000 pounds option, because it directly reflects the given tensile force to be used in any related calculations or comparisons. The other numbers would imply different loads that aren’t supported by the data provided.
