A calculate the tension in a vertical strand of spiderweb, Ask an Expert

Academics

(a) Calculate the tension in a vertical strand of spiderweb if a spider of mass 8.00 x 10^-5 kg hangs motionless on it.

(b) Calculate the tension in a horizontal strand of spiderweb if the same spider sits motionless in the middle of it much like the tightrope walker in Figure. The strand sags at an angle of 15.0^o below the horizontal.

Compare this with the tension in the vertical strand (find their ratio).
