In the figure below, the current in the long, straight wire is 11 7.00 A and the wire lies in the plane of the rectangular loop, which carries a current 12-10.0 A. The dimensions in the figure are c0.100 m, a 0.150 m, and 0.510 m. Find the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire magnitude directionSelect UN /2 Need Help?Read ItMaster It
A hollow shaft 36 inches long transmits 110 HP at 1300 rpm. The shaft is made out of steel with a modulus of rigidity of 11000 ksi. The shaft has an allowable sear stress of 12 ksi and an allowable angle of twist of 2.5 degrees over the 36 inches length. The inside diameter of the shaft is 0.65 that of the outside diameter of the shaft. Determine: a) the required inside and outside diameter of the shaft based on...
