Does negative pressure respirator brings fresh air to you through a hose? An example of a negative pressure respirator is the disposable N95 filtering face-piece respirator. Therefore, a negative pressure respirator brings fresh air to you through a face-piece, not through a hose. What does a negative pressure respirator do? A negative pressure device depends […]
Why must the charge in the combustion chamber be compressed before ignition?
Why must the charge in the combustion chamber be compressed before ignition? The charge is the volume of compressed air-fuel mixture trapped inside the combustion chamber ready for ignition. Compressing the air-fuel mixture allows more energy to be released when the charge is ignited. Intake and exhaust valves must be closed to ensure that the […]
What is stress and strain in materials?
What is stress and strain in materials? Stress is the force applied to a material, divided by the material’s cross-sectional area. σ = stress (N/m2, Pa) F = force (N) A0 = original cross-sectional area (m2) Strain is the deformation or displacement of material that results from an applied stress. What is stress strain curve […]

How do you identify a transfer function from a filter?
How do you identify a transfer function from a filter? You can look at the values of the transfer function as frequency approaches zero and infinity. A low-pass-filter transfer function will go to zero as frequency approaches infinity while a high-pass filter will not. What is the transfer function of a low-pass filter? This transfer […]

Which of these should not be done with sharps?
Which of these should not be done with sharps? DON’T throw loose needles and other sharps into the trash. DON’T flush needles and other sharps down the toilet. DON’T put needles and other sharps in your recycling bin — they are not recyclable. DON’T try to remove, bend, break, or recap needles used by another […]
When inductors are connected in series in a circuit the total inductance is?
When inductors are connected in series in a circuit the total inductance is? When inductors are connected in series, the total inductance is the sum of the individual inductors’ inductances. To understand why this is so, consider the following: the definitive measure of inductance is the amount of voltage dropped across an inductor for a […]
