Forces — practice question

Fig. 3.1 presents a central cross-section of a solid cone alongside a central cross-section of a solid cuboid. In Fig. 3.1, the cone and the cuboid are shown resting on the ground. The solid cone is the more stable object. The symbol x marks the location of the centre of gravity for each object.
(a)[1]

Explain why the solid cone in Fig. 3.1 is more stable than the solid cuboid.

(b)[3]

Calculate the pressure produced by the solid cuboid on the ground.

(c)[3]

Calculate the moment of the 15 N force about the pivot.
