Image transcription text81. A bag fif cement hangs from three wires as shown in Fig- ure P4.81. Two of the wires make angles 6, and 6y, respec- tively,
with the horizontal. (a) Show that, if the system is in equilibrium, then w cos B – sin( 6, + 6,) (b) Given that w = 325 N, 6, = 10.0°,
and #s = 25.0°, find the tensions T}, 7o, and T3 in the wires. ; Figure P4.81 … Show more
