Question

The distance between two telephone poles is 59 m. When a 1.47 kg bird lands on the telephone wire midway between the poles, the wire sags 0.117 m. The acceleration of gravity is 9.8 m/s How much tension in the wire does the bird produce? Ignore the weight of the wire. Answer in units of N. 002 (part 1 of 2) 10.0 points Consider a 775 N cat burglar supported by a cable as in the figure. 37° Find the tension in the inclined cable Answer in units of N 003 (part 2 of 2) 10.0 points Find the tension in the horizontal cable. Answer in units of N.

Explanation / Answer

1)

mg - 2T*cos(theta)

T = mg / 2cos(theta)

tan(theta) = 29.5 / 0.117

theta = 89.77 degree

T = (1.47 kg x 9.81 m/s^2) / 2cos(89.96)

T = 1818 N
