Two of the wires make angles 1 = 59.0° and 2 = 43.0° with the horizontal. Assuming the system is in equilibrium, find the tensions T1, T2, and T3 in the wires. T3 = Ti Ts

Explanation / Answer

on mass: Fnet = T3 - m g = 0

T3 = 400 N ..........Ans

balancing forces in horizontal,

T2 cos43 - T1 cos59 = 0

T2 = 0.704 T1

in vertical, T1 sin59 + T2 sin43 - T3 = 0

T1 sin(59) + (0.704 T1) sin43 = 400

T1 = 299 N ........Ans

T2 = 210.6 N ......Ans
