Solution а) Let us first derive the expression for the tension. By Newton's First Law ΣF the components of force that makes this so is ΣFT = 0 Simplifying this results to T= g/ (4) Analyzing the figure above, we arrive at (4) sqt( 2+ %3D + By substitution, we arrive at the following: T = + 2 )g/( sqrt ( )) + If the ball has a mass of 45 kg and diameter 32 cm, while the wire has a lenath of 30 cm. The tension is equal to For Blank 17 0.370 N T =
