1.A chair attached to a vertical rotating pole by two cables, is spun in a horizontal circle at a constant speed. The speed is sufficient to create tension in both the upper and lower cables. The tension in the upper cable is 3500N, L=10 m, and the mass of the chair is 134kg.
c. Predict which tension force is greater, T1(tension in the upper cable) or T2 (tension in the lower cable).
d. What is the tension in the lower cable?
2. Homework Equations
Mathematical equations for equilateral triangle
like height =(((3)^0.5)/2)x side
and F=ma equation
3. The Attempt at a Solution
for c, I think upper cable has more tension
and for d, I just found the vertical component of the upper cable, and also the weight of the chair, and assumed that the vertical component of the lower cable is vertical comp of the upper cable minus the Weight
wondering if i am right in my assumption?
