A uniformly-dense equilateral triangle with weights hanging from each vertex is fixed at its center of mass as shown below: The triangle has a mass of 2kg and each side has a length of 0.50 meters, and it is held so that the vertex connected to F, is at an angle of 45° from the horizontal. All weights hang vertically downwards, where F=25 N, F2=15 N and F3=10 N. What is the magnitude of the angular acceleration when the triangle is released and allowed to rotate, in rad/s?? Justify your answer with your rationale and equations used. Itriangle = MI? T%3= Hint: Be careful with the angles you use for your calculation! Remember what the angle between vertexes of an equilateral triangle are.
