Physics Tension Question?
If a sign with a mass of 10 kg (FG = 98N), if the first cord is at a angle of 35 degrees from the horizontal and the second cord is 65 degrees from the horizontal, what is the total tension in the cord? Since you have angles and the Normal force (opposite of Fg right)?. Once you find both tensions, do you add them both up then divide by 2? I am so confused for my test tomorrow.
Thanks, Jo-eL

EZ
let tension T1 in cord is at a angle of 35 degrees and T2 in cord is 65 degrees from the horizontal
horizontally,
T1 cos 35 = T2 cos 65 -----(1)
vertically,
T1 sin 35 + T2 sin 65 = 98 -----(2)
from (1)
T1 = T2 * cos 65 / cos 35
sub into (2) and solve for T2 and and than T1 ----answer
