Question 1 Report
The diagram above shows a solid figure with base PQ and center of gravity G on a inclined plane. Which of the following statements is correct
Answer Details
The stability of a solid placed on an inclined plane depends on the position of its center of gravity with respect to the base. The base of the solid is the polygon formed by the intersection of the solid and the plane on which it rests. The center of gravity of the solid is the point where its weight can be considered to act.
If the vertical line through the center of gravity G falls within the base PQ, the solid will be in a stable equilibrium, meaning it will not fall over. However, if the vertical line through G falls outside the base, the solid will be in an unstable equilibrium, meaning it will topple over.
Therefore, option (A) is the correct statement: "The solid will fall over if the vertical line through G lies outside the base."
