What is the difference between a thermoplastic and a thermosetting plastic? Thermosoftening (also called thermoplastics) are plastics which will soften when heated and can be reshaped. Thermosetting plastics are plastics do not soften on heating. They are used when resistance to heat is important (eg kettles, plugs, laptop chargers etc). What are the main differences […]
How do you find the transfer function of a closed loop system?
How do you find the transfer function of a closed loop system? Closed-loop System Transfer Function To find the transfer function of the closed-loop system above, we must first calculate the output signal θo in terms of the input signal θi. Note that the error signal, θe is also the input to the feed-forward block: […]
How do you find the standard deviation of a uniform distribution?
How do you find the standard deviation of a uniform distribution? The standard deviation of X is σ=√(b−a)212. The probability density function of X is f(x)=1b−a for a≤x≤b. The cumulative distribution function of X is P(X≤x)=x−ab−a. How do you find the standard deviation of a random variable X? For a discrete random variable the standard […]
How do you find the multiplicity of a root?
How do you find the multiplicity of a root? The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, x=2 , has multiplicity 2 because the factor (x−2) occurs twice. The x-intercept x=−1 is the repeated solution […]
What is meant by Schottky defect?
What is meant by Schottky defect? A Schottky defect is an excitation of the site occupations in a crystal lattice leading to point defects named after Walter H. In ionic crystals, this defect forms when oppositely charged ions leave their lattice sites and become incorporated for instance at the surface, creating oppositely charged vacancies. What […]
What are the 4 uses of energy?
What are the 4 uses of energy? We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy. What do we use […]
What causes high total harmonic distortion?
What causes high total harmonic distortion? Harmonic distortions are usually caused by the use of nonlinear loads by the end users of electricity. Nonlinear loads, a vast majority of which are loads with power electronic devices, draw current in a nonsinusoidal manner. What does total harmonic distortion mean? From Wikipedia, the free encyclopedia. The total […]

When removing and replacing piston rings on a cast aluminum alloy piston The technician should?
When removing and replacing piston rings on a cast aluminum alloy piston The technician should? 2. When removing and replacing piston rings on a cast aluminum alloy piston, the technician should: Use the old ring and a feeler gauge to measure piston ring groove clearance. When installing a piston assembly the notch on the head […]
