Question 1 of 27070

The center of gravity of a freely swinging load suspended from a pedestal crane acts as if it were located at the __________.

🔍 Key Concepts

• Center of gravity (G) of a suspended body • Behavior of a freely swinging load (like a pendulum) • Relationship between the load and its point of suspension on a crane

💭 Think About

• Imagine the load swinging like a pendulum: if you replaced the entire load with a single point mass, where would that point be attached so that the motion is the same? • Think about where the weight of the load is effectively carried by the crane structure—what exact point on the crane feels the entire load? • Which choice best represents the place about which the load can freely swing in any direction?

✅ Before You Answer

• Focus on the load–hook connection, not the internal structure of the crane • Identify which option is the exact location where the load is attached and allowed to swing freely • Eliminate any answer that describes a general part of the crane structure and not the actual attachment/swing point
