A very light tripod has 70 centimeter long legs that can be spread out so that each makes a 20 degree angle with the vertical. The points where the three legs rest on the ground form an equilateral triangle.
If you attach an object to the tripod, such as a camera with along lens, determine the maximum possible horizontal distance between the center of gravity of the object and the center of the tripod, if the tripod is to remain stable?
