a load is unknown weight is suspended from end of a horizontal boom, the weight of which is negligible . the angle between the boom and the cable supporting its end 30 degrees the tension in the cable is 400n . what is the tension of the rope ?
+36916 The vertical component of the 400 N is supporting , and equal to the load
400 sin30 = 200 N
200N/9.81 m/s^2 = 20.4 kg
