Find a real physical example of a mechanical structure or machine that has a moment acting on it.

(a) Make a clear, labeled drawing of the situation.

(b) Estimate the dimensions, and the magnitudes and directions of the forces that act on it. Show these on your drawing. Briefl y explain why you estimate the dimensions and forces to have the numerical values that you assigned.

(c) Select a moment pivot point, explain why you chose that point (perhaps it is important from the standpoint of the structure or machine not breaking), and estimate the moment produced about that point.
