The greatest horizontal stress between the heads of the booms in the yard and stay rig occurs when the load is in such a position that the __________.

🔍 Key Concepts

• Vector forces in booms and falls (horizontal vs vertical components) • Relationship between angle of a fall to the horizontal and the size of its horizontal force component • How opposing horizontal components between yard and stay falls create stress between boom heads

💭 Think About

• Think about what happens to the horizontal component of the force in a fall as its angle to the horizontal becomes larger or smaller. • Picture the two boom heads with the load somewhere between them: in which load position would the sideways pull between boom heads be the strongest? • Compare a situation where one fall is nearly vertical and the other more shallow to one where both falls share the pull more evenly. Which gives the greatest sideways (horizontal) push or pull between the heads?

✅ Before You Answer

• For each choice, mentally resolve the force in each fall into horizontal and vertical components. • Check which option would make the horizontal components from the two falls largest and most opposed to each other. • Verify whether having one fall more vertical and the other more horizontal reduces or increases the horizontal stress between boom heads.
