2. Consider the volleyball pole shown in the figure below. The volleyball net exerts a horizontal force of 120 N to the left at a height of 1.8 m. A support wire is attached to the pole at a height of 2.5 m and runs down to the ground where it makes an angle of 54° with respect to the horizontal. Assuming that the ground does not apply a torque to the pole, what is the tension in the cable? pole F= 120 N 2.5m 1.8m B C D E 107 N 137 N 159 N 147 N 129 N

Answer 1

Oliven data:- F=120N he= 1.8m, h=2.5m. O=54. Counter clockwise torque = f(he) = 120x1.8 = 216 Nm. Clockwise Torque - Tcos(@y)(2.) Tcos(542.5 = 216 T= 216 Cos(540) 2.5 = 147N. : (1= 1470
