What is T?

A bag of cement weighing 525 N hangs in equilibrium from three wires as suggested in the figure below. Two of the wires make angles 0, = 62.0° and 0, = 43.0° with the horizontal. Assuming the system is in equilibrium, find the tensions T,, T,, and T, in the wires. 269.42 T = Consider the net force at the point where the three wires come together. What is the acceleration of this point? N 420.98 Ta = The horizontal component of your T, is not equal to the horizontal component of your T,, so the object would be accelerating horizontally.
