How do you calculate shaft diameter from torque? Inputs that we need to calculate shaft diameter τ = Torsional stress induced at the outer surface of the shaft (Maximum Shear stress). r = Radius of the shaft. T = Twisting Moment or Torque. J = Polar moment of inertia. C = Modulus of rigidity for […]
What is controllable system?
What is controllable system? A system is controllable if it can move from any state to any other state in finite time. How do you tell if a system is controllable or observable? A system is said to be completely observable if all the possible initial states of the system can be observed. Systems that […]
What is the best way to get water out of diesel fuel?
What is an isolated system example?
What is an isolated system example? A thermos flask is the best example of an isolated system. A thermos flask is used to keep things either cold or hot. Thus a thermos does not allow energy for transfer. An isolated system does not exchange energy or matter with its surroundings. What is meant by an […]

What supports the overhanging bricks in the accompanying image? A hidden lintel (like a steel angle). What is Rowlock brick? Rowlock. A brick laid on its face, or edge. Soldier. A brick laid on its end […]
What is the rms value of full wave rectifier?
What is the rms value of full wave rectifier? Full-wave Rectifier Average Value Then we can see that a full-wave rectifier circuit converts BOTH the positive or negative halves of an AC waveform into a pulsed DC output that has a value of 0.637*AMAX or 0.9*ARMS as shown. How do you calculate the average voltage […]
Why do ionic compounds conduct electricity in aqueous solution and not in solid state?
Why do ionic compounds conduct electricity in aqueous solution and not in solid state? Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and […]
How do you read a screw thread callout?
How do you read a screw thread callout? Here are the five steps to interpreting thread callout: Look at the numbers in the callout. Understand the first number in the callout – This indicates the major diameter. Understand the second number in the callout – This indicates the distance between threads. Read the length – […]
What is refrigerator in thermodynamics?
What is refrigerator in thermodynamics? A refrigerator is a device which is designed to remove heat from a space that is at lower temperature than its surroundings. The same device can be used to heat a volume that is at higher temperature than the surroundings. In this case the device is called a Heat Pump. […]
