A solid uniform ball with mass m and diameter d is supported against a vertical frictionless wall by a thin massless wire of length L. a) Find the tension in the wire. Solution a) Let us first derive the expression for the tension. By Newton's First Law ZF = the components of force that makes this so is EF = T = 0 Simplifying this results to 8/ (4) Analyzing the figure above, we arrive at (4) = sqrt( By substitution, we arrive at the following: T= + 2 Og/( sqrt ( 24 If the ball has a mass of 45 kg and diameter 32 cm, while the wire has a length of 30 cm. The tension is equal to T- 0.370 N
