A picture frame is hanging by two vertical strings. The tensions in the strings are 3.8 N and 4.4 N. Find the weight of the picture frame. (8.2 N)

Solution:Tension $T_{1}$ = 3.8 NTension $T_{2}$ = 4.4 NWeight of the picture frame = w =? When the picture is in equilibrium, then ∑ $F_{x}$ = 0 and ∑ $F_{y}$ = 0Therefore T – w = 0 Or $(T_{1} + T_{2})$ – w = 0              $T_{1} + T_{2}$ = w          3.8 + 4.4 = w                    W = 8.2 N
