When the outside air temperature is 80°F, what is the acceptable tension range for a 3/16 cable?

The acceptable tension range for a 3/16 cable at an outside air temperature of 80°F is crucial for ensuring proper safety and performance in assembly and rigging operations. The correct answer reflects the specific engineering guidelines and manufacturer specifications that dictate required tension levels to maintain the integrity of the cable under varying environmental conditions.

The tension range provided ensures that the cable is neither too loose, which could lead to a loss of control or failure to transmit loads properly, nor too tight, which could risk damaging the cable due to excess strain or reduce its lifespan.

At 80°F, a tension specification of 117 pounds minimum and 143 pounds maximum takes into account the material properties of the cable and the potential effects of temperature on its strength. High temperatures may affect cable flexibility and tension retention, so adhering to these metrics is essential for safety and efficacy.

Therefore, the appropriate tension range represented in this choice aligns well with accepted engineering standards and ensures optimal performance for the cable in the specified conditions. This understanding of material behavior in response to environmental factors is critical for anyone working with assembly and rigging.
