What is the best way to prevent skidding on a slippery road surface? To prevent skidding on slippery surfaces: Drive slowly and stay farther behind the vehicle ahead of you. Slow down as you approach curves and intersections. Avoid fast turns. Avoid quick stops. Shift to low gear before going down a steep hill. Which […]
What is composite fabrication?
What is composite fabrication? Composite fabrication processes typically involve some form of molding, to shape the resin and reinforcement. A mold tool is required to give the unformed resin/fiber combination its shape prior to and during cure. How do you manufacture composite materials? Composite materials are processed and cured inside a vacuum bag or a […]
What is signalized intersection?
What is signalized intersection? A signalized intersection is one where the shared space is used alternatively by a fixed number of approaches for a pre defined time interval as per the phasing scheme used for the intersec- tion. What is a protected left turn what is an unprotected left turn? Standard Green Light (called Unprotected […]
What is the compression of a 2-stroke engine?
What is the compression of a 2-stroke engine? between 90 and 110 psi What is the compression stroke on an engine? : the stroke in the cycle of an internal-combustion engine in which the gases are compressed before firing. What is the first stroke of an engine? induction stroke What are the strokes of a […]
What percentage of missing data is acceptable?
What percentage of missing data is acceptable? Statistical guidance articles have stated that bias is likely in analyses with more than 10% missingness and that if more than 40% data are missing in important variables then results should only be considered as hypothesis generating [18], [19]. What happens when a dataset includes with missing data? […]
What is Ficks first law diffusion?
What is Ficks first law diffusion? Fick’s 1st law of diffusion Diffusion occurs in response to a concentration gradient expressed as the change in concentration due to a change in position, . in which the flux J [cm-2 s-1] is proportional to the diffusivity [cm2/s] and the negative gradient of concentration, [cm-3 cm-1] or [cm-4]. […]
How do you increase thrust?
How do you increase thrust? The most widely recognized method of boosting thrust is the afterburner, also known as tailpipe burning. Fuel is injected into the hot exhaust gas flowing between the turbine and nozzle. The combustion of the gas expands the airflow as it enters the nozzle, which increases thrust. Does thrust increase lift? […]
What is an oil additive give any two additive?
What is an oil additive give any two additive? Controlling chemical breakdown Typical detergents are magnesium sulfonates. Corrosion or rust inhibiting additives retard the oxidation of metals inside an engine. Antioxidant additives retard the degradation of the oil stock by oxidation. Typical additives are organic amines and phenols. What are oil additives? Motor oil additives […]
What are the two types of fluid flow?
What are the two types of fluid flow? Types of Fluid Flow Fluid flow is generally broken down into two different types of flows, laminar flow and turbulent flow. Laminar flow is fluid motion in which all the particles in the fluid are moving in a straight line. Why is fluid flow important? Fluid dynamics […]
What do you understand by structural system of a building?
What do you understand by structural system of a building? Structural system, in building construction, the particular method of assembling and constructing structural elements of a building so that they support and transmit applied loads safely to the ground without exceeding the allowable stresses in the members. Why is it important to know the structural […]
