A block of weight Wis supported by three strings asshown in figure. Which of the following relations istrue for tension in the strings? (Here T, T2 and 7,are the tension in the strings A, Band C respectively)135B(2) T, T(3)Te= 7,2 3

Answer»

Block of weight W is supported by three strings A,B and CHence the Block is in equilibrium.Hence by applying Lami's theorem we have,T3/sin135=T2/sin90=T1/sin135

T3/sin135=T1/sin135

T3=T1

Hence T3=T1
