A) you are investigating the electrical testing
circuits and find that, in an inductive circuit, the relationship
between instantaneous current i( 2.1amps) and the time t(
1-e⁻9t)
you have been asked to determine the time taken for the current to
raise from 1 to 1.45 amps
B) the drive system of a conveyor used to transport
the engine parts is made up of an open belt which passes over two
pulleys have diameter of 200mm and 320mm respectively and the
distance centres is 650mm
you have been asked to determine the length of the belt, using
trigonometric techniques, assuming the belt is in tension.
C) An electrical cable is to be suspended across two machines. the machine are a distance L=3.35 meters apart. the cable forms the shape of a catenary of the form y=c cost (x/c) where x = L/2. you have been asked to determine the fixing point heivht(y) if the minimum clearance (c) is to be 3m at the centre of the catenary
generate all the answers from contextualized arithmetic and geometric progressions..

You are working in a factory and have been tasked with determining the electrical needs for a new motor that will be installed on an assembly line. The motor has been tested under load conditions and found to have a resistance of 37.0 2 and an inductive reactance of 51.0 12. We can model the motor as a series RL circuit. The motor will have its own dedicated circuit with an rms voltage of 540 V. You need to determine...

On your first day at work as an electrical technician, you are asked to determine the resistance per meter of a long piece of wire. The company you work for is poorly equipped. You find a battery, a voltmeter, and an ammeter, but no meter for directly measuring resistance (an ohmmeter). You put the leads from the voltmeter across the terminals of the battery, and the meter reads 12.6 volts. You get a 100-meter spool of wire and connect it...

(25 points) As a junior roadway engineer, you have been asked to
contribute to the design of a section of roadway that runs through
a national park. An endangered deer population has been identified
in the area and a wildlife underpass under a vertical curve has
been proposed, as shown in the figure below. An existing underpass
is perpendicular to the roadway at station 20+91.00 (not
necessarily under the center of the curve). The top of the
underpass...

You have been asked to design a magnetic trap for your summer internship. (a) First, consider a circular loop of wire of radius R located in the xz plane and carrying a steady current. Determine the magnetic field at an axial point P a distance x from the center of the loop. (Make sure to include a sketch.) (b) But, one loop isn’t going to get you enough B field strength, so you have to wrap 48 loops (8 layers...
