Specify the range of specific magnetic loading and electric loading in an induction motor. Specific magnetic loading = 0.3 to 0.6 Wb/m2Specific electric loading = 5000 to 45,000 AT/m 2. Why the stator of a three-phase induction motor is laminated? Lamination is usually done in stator teeth and stator core of stator to decrease the iron (eddy current) losses in the induction motor.
Two couples act on the frame. d = 4 ft. (Figure 1) Part A Determine the couple moment of the 80-lb forces. Express your answer in terms of the unit vectors i, j, and k. Use the 'vec' button to denote vectors in your answers. Express your answer using three significant figures. Part B Determine the couple moment of the 50-lb forces. Express your answer in terms of the unit vectors i, j, and k. Use...
ollar B moves downward to the left with a constant velocity of 1.6 m/s. At the instant shown when u = 40°, determine (a) the angular velocity of rod AB, (b) the velocity of collar A. Collar A moves upward with a constant velocity of 1.2 m/s. At the instant shown when u = 25°, determine (a) the angular velocity of rod AB, (b) the velocity of collar B.
A natural gas mixture having a molar analysis 60% CH4, 30% C2H6, 10% N2 is supplied to a furnace like the one shown in Fig. P13.8, where it burns completely with 20% excess air. Determine (a) the balanced reaction equation. (b) the air–fuel ratio, both on a molar and a mass basis. A gas mixture with the molar analysis 25% H2, 25% CO, 50% O2 reacts to form products consisting of CO2, H2O, and O2...
||The starter motor of a car engine draws a current of 150 A from the battery. The copper wire to the motor is 5.0 mm in diameter and 1.2 m long. The starter motor runs for 0.80 s until the car engine starts. a. How much charge passes through the starter motor? b. How far does an electron travel along the wire while the starter motor is on?
Use the Method of Consistent Deformation to analyse the planar truss shown in Figure 02 Select the reaction Cy at the roller support C to be the redundant. Note that Ni-N, are the member forces in the statically indeterminate truss. Assume that all members have the same EA. 20 kN Figure Q2 3 m N. p/6 B 18, Answer
Write a net ionic equation to show that ascorbic acid, H2C6H6O6, behaves as an acid in water. Consider only its first ionization.
The tractor boom supports the uniform mass of 600 kg in the bucket which has a center of mass at G. Determine force in each hydraulic cylinder AB and CD and the resultant force at pins E and F. The load is supported equally on each side of the tractor by a similar mechanism.
Despite many attempts, the perbromate ion ( BrO4-) was not prepared in the laboratory until about 1970. (In fact, articles were published explaining theoretically why it could never be prepared!) Draw a Lewis structure for BrO4 - in which all atoms have lowest formal charges. Phosgene is a colorless, highly toxic gas that was employed against troops in World War I and is used today as a key...
