Explanation
ফ্লিপ-ফ্লপ (Flip-flop) হলো একটি ডিজিটাল লজিক সার্কিট যা ১ বিট বাইনারি ডেটা (0 বা 1) সংরক্ষণ করতে পারে। এটি মেমোরি এলিমেন্ট হিসেবে কাজ করে।
Explanation
The maximum gradient for roads typically ranges depending on terrain, but standard guidelines often limit the ruling gradient to around 4% (1 in 25) to 5% for safe vehicular movement.
Explanation
Herring-bone bond is a pattern of bricklaying used primarily for brick paving (flooring) or decorative panels, where bricks are laid at a 45-degree angle to the direction of the path.
Explanation
Chlorinated copper is not a standard coagulant. Common coagulants include alum, ferric chloride, and ferric sulphate. Copper compounds are toxic and generally used as algaecides, not coagulants.
Explanation
Aggregates (sand, gravel) act as an inert filler material in concrete. They provide bulk, reduce shrinkage, and are cheaper than cement, while the cement paste binds them together.
Explanation
Exit gradient is the hydraulic gradient at the downstream end of a flow line. It is defined as the ratio of head loss (Δh) to the length of seepage (l) as the water exits the soil.
Explanation
Biochemical treatment (like activated sludge) relies on microorganisms to consume organic matter. This is an oxidation process where organic carbon is oxidized to CO2 and new biomass in the presence of oxygen.
Explanation
In an under-reinforced section, the amount of steel is less than the balanced amount. This ensures that the steel yields (fails) before the concrete crushes, providing a ductile failure with warning.
Explanation
A three-hinged arch has hinges at both supports and one at the crown. This makes it a statically determinate structure, meaning its reactions can be calculated using equilibrium equations alone.
Explanation
Concurrent forces are a set of forces whose lines of action all intersect at a common single point, although they may not necessarily lie in the same plane.
