Three men pull on ropes attached to the top of a heavy object which is level with the ground. Man A is 183 cm tall, stands 183 cm away, 45 deg N of E from the center of the object and exerts a force of 320 N. Man B is 168 cm tall, is 183 cm away, 60 deg N of W and pulls with a force of 267 N. Man C is 152 cm tall, also stands 183 cm away, 30 deg S of E and pulls with a force of 356 N. Assuming the ropes to be attached to their shoulders which are 2/3 of their height from the ground, what is the horizontal resultant of these forces on the object?
