Question

(a) Find the tension in each cable. inclined cable N horizontal cable N vertical cable N
(b) Suppose the horizontal cable were reattached higher up on thewall. Would the tension in the inclined cable increase, decrease,or stay the same?
increasedecrease    staythe same increasedecrease    staythe same increasedecrease    staythe same inclined cable N horizontal cable N vertical cable N

Explanation / Answer

The components are      T1 cos30 = T2      T1 sin30 = T3 T3 = 700      ==> T1 = 700 / sin30 = 1400N(inclined cable)             T2 = 1400 * cos30 = 1212.4 N (Horizontal )             T3 = 700 N (vertical) b) decreases.
