Two falls are supporting a 1.5 ton load. The port fall is at an angle of 40° from the vertical. The starboard fall is at an angle of 70° from the vertical. What is the stress on each fall?

Correct Answer: Option A — Port 1.5 tons, starboard 1.0 tons

Resolving vertical and horizontal force vectors for a 1.5-ton load supported by two angled falls determines the tension. Using equilibrium equations results in 1.5 tons of stress on the port fall and 1.0 ton on the starboard fall.
