Bars AB and BC lie in the horizontal x-y plane, and the third bar lies in a plane parallel to the x-z plane. Compute the tension in each wire. 1040 m 520 mm 520 mmy 1040 mm30 Answer: ir:
A conducting bar, having a mass per unit length of 0.0400 kg/m, is suspended by two flexible conductive wires of negligible mass, hanging from the ceiling (insulated) as shown below, What is the magnitude and direction of the current, I, that must exist in the conductor for the tension in the supporting wires to be zero when the magnetic field is 3.60 T into the page? If the resistance of the conductor is 0.200 ohm, what is the emf in...
In a butcher shop, a horizontal steel bar of mass 3.92 kg and length 1.40m is supported by two vertical wires attached to its ends. The butcher hangs a sausage of mass 2.34kg from a hook that is at a distance of 0.20m from the left end of the bar. What are the denotes the tension in the right wire.
