(a) Find the tension in each cable supporting the 548-N cat burglar. (Assume the angle ? of the inclined cable is 35.0°.)
inclined cable N
horizontal cable N
vertical cable N

(b) Suppose the horizontal cable were reattached higher up on the wall. Would the tension in the inclined cable increase, decrease, or stay the same?

increase

decrease

stay the same

Explanation / Answer

The components are T1 cos35 = T2 T1 sin35 = T3 T3 = 548 ==> T1 = 548 / sin35 = 955.41 (inclined cable) T2 = 955.41 * cos35 = 782.62 N (Horizontal ) T3 = 548 N (vertical) b) decreases.
