Question

Arlene is to walk across a high wire strung horizontally between two buildings 11.0 m apart. The sag in the rope when she is at the midpoint is 10.0°, as shown in Figure 4-42. If her mass is 58.0 kg, what is the tension in the rope at this point?
N

Answer 1

Writing equation for vertical forces
Weight - vertical tension component on the left and to the right.

mg -Tsin(10) - Tsin(10)

T=2mg/sin(10)

T=1640 N
