a 5kg ball is suspended by two strings one horizontally attached to a wall and one attached to the ceiling at a 35 degree angle, determine the tension in the slanted string, determine the tension in the horizontal string (you have to use a free body diagram).

Answer 1

The system is in Equilibrium.

The sum of all hor. forces = 0:
T1*Cos(180-35) + T2 = 0.
-0.819T1 = -T2, T1 = 1.22T2.

The sum of all vert. forces = 0:
T1*sin(180-35) + (-5) = 0,
0.574T1 = 5, T1 = 8.72 kg.

1.22T2 = 8.72, T2 = 7.15 kg.
