(2009? Figure (a) is an action in the acrobatic ballet Swan Dance. In order to estimate the pull required by the actor who plays the prince's right hand,

Force analysis is shown in the figure.

Taking o as the axis: m inverse =M shun

m 1g×OC = f×ob×sinθ+m2g×ob2oc×cosθ

36× 10×0.4 = f×0.7×sin 45+8× 10×0.35×cos 45

F≈250.92N

A: the horizontal tension f is 250.92 n.
