1) A wardrobe is $2$m high and $1.6$m wide. When empty, it has a mass of $110$kg and its centre of gravity is $0.8$m above the centre of its base. What is the minimum angle through which it must be tipped before it will continue to fall by itself? 2) Tall vehicles should have as low a centre of mass as possible. Why? Is it because of tipping over? I understand what moment, couple, torque is but I am having difficulty answering these questions. |

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.

With a simple diagram do the sum of the forces equals zero and the sum of the moments equals zero. Consider two points of contacts on the ends of the part. Under what conditions the contact force becomes negative which is physically impossible and tipping would occur? Please show us what your have tried first. |
