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 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 […]
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 […]
Which brick manufacturing process produces a molded brick?
Which brick manufacturing process produces a molded brick? extrusion process What supports the overhanging bricks in the accompanying image? 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 laser and its principle?
What is laser and its principle? The principle of laser amplification is stimulated emission. If the gain is larger than the losses, the power of the light in the laser resonator rises very rapidly, starting e.g. with low levels of light from fluorescence. What is the full meaning of laser? light amplification by stimulated emission […]
What happens to the working distance as you increase magnification?
What happens to the working distance as you increase magnification? Working distance is how much space exists between the objective lens and the specimen on the slide. As you increase the magnification by changing to a higher power lens, the working distance decreases and you will see a much smaller slice of the specimen. What […]
What is meant by stress strain diagram?
What is meant by stress strain diagram? Stress strain curves visually display the material’s deformation in response to a tensile, compressive, or torsional load. Depending on the material being tested, a stress strain curve can indicate key properties of the material including its elastic region, plastic region, yield point, and ultimate tensile strength. What is […]
