5.0° 5.0° т. У TA Figure 4.17 The weight of a tightrope walker causes a wire to sag by 5.0 degrees. The system of interest here is the point in the wire at which the
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
Calculate the tension in a vertical strand of spider web
if a spider of mass 8.00×10−5 kg hangs motionless on it.
(b) Calculate the tension in a horizontal strand of spider web if
the same spider sits motionless in the middle of it much like
the tightrope walker . The strand sags at an
angle of 12º below the horizontal. Compare this with the
tension in the vertical strand (find their ratio).
