Question

2. An electrical lamp weight 20N hangs from a point C by two strings AC and BC as shown in fig 1. Find the force in strings.​

Answer 1

Answer:

First draw the F.B.D. of the electric light fixture, Apply lami's theorem at point ‘C T1/sin 150° = T2/sin 135° = 15/sin 75° T1 = 15.sin 150°/ sin 75° T1 = 7.76 N T2 = 15. sin 135°/ sin 75° T2 = 10.98 . PLS SEMD DIAGRAM ALSO
