A light string has its ends tied to two walls separated by a distance equal to three-fifths the length of the string as shown in the figure. An 18 kg mass is suspended from the center of the string, applying a tension in the string. What is the tension in the two strings of length L 2 tied to the wall? The acceleration of gravity is 9.8 m/s 2 . Answer in units of N
Homework Answers
theta = arccos[(3L/10) / (L/2)]
theta = 53.13o
The vertical components of the tension (two strings) = the weight of the block.
2*T*sin(53.13) = (18)(9.8)
T = 110.25 N
