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?

Question

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

Accepted Answer

Option A: Port 1.5 tons, starboard 1.0 tons. Resolving forces in a multi-fall lifting system using trigonometric load distribution formulas for a 1.5-ton load with falls at 40 and 70 degrees from the vertical results in 1.5 tons on the port fall and 1.0 ton on the starboard fall.
