What is consolidation settlement in soil? Settlements refer to the soil’s movement in the vertical direction typically induced by stress changes. Since soil particles are practically incompressible, consolidation settlements is caused by a reduction in voids due to gradual squeezing out of water. What is compaction? Compaction is what happens when something is crushed or […]
What are the advantages of wind tunnel testing?
What are the advantages of wind tunnel testing? Scale Model Wind Tunnel Testing has many advantages. Correlation between model results and actual track performance can be excellent. Accuracy. Speed of development. Flexibility of testing. Compared to full scale testing, the cost of test parts is much reduced as is the time in which they can […]
How does dielectric breakdown occur?
How does dielectric breakdown occur? Dielectric breakdown occurs when electrical potential across a material exceeds the dielectric strength of the material, resulting in partial ionization. If breakdown occurs in a gas, the ionization sharply reduces the electrical insulation properties of the gas, resulting in a spark or arc. What is meant by dielectric breakdown? Dielectric […]
Why did the teacher punish you change into passive voice?
Why did the teacher punish you change into passive voice? Answer. if the sentence in active voice is ‘Why did the teacher punish him?’ Then on converting it into passive voice it will become ‘why was he punished by the teacher’. Passive voice sentences shows the interest in the person or action that experience an […]
What is meant by aerodynamic drag?
What is meant by aerodynamic drag? Drag is the aerodynamic force that opposes an aircraft’s motion through the air. If there is no fluid, there is no drag. Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there […]
What are the characteristics of computers?
What are the characteristics of computers? Characteristics of Computer System Speed. A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations. Accuracy. Computers perform calculations with 100% accuracy. Diligence. A computer can perform millions of tasks or calculations with the same consistency and accuracy. Versatility. Reliability. Memory. What are […]
What happen if resistor and capacitor are connected in series?
What happen if resistor and capacitor are connected in series? If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across it reaches that of the supply voltage. The time required for the capacitor to be fully charge is […]
What is beam model?
What is beam model? BEAM is a framework for discussing the usefulness of different types resources. Developed by Joseph Bizup as a more functional alternative to the traditional primary/secondary classification, BEAM stands for Background, Exhibit, Argument, and Method. Where are beams used? Beams primarily carry vertical gravitational forces. They are also used to carry horizontal […]
What is the process of cryptography?
What is the process of cryptography? Definition: Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. Cryptography is used in many applications like banking transactions cards, computer passwords, and e- commerce transactions. Three types of cryptographic techniques used in general. What are the three types of encryption? The […]
What is the main cause of brake fade under prolonged heavy brake application?
What is the main cause of brake fade under prolonged heavy brake application? Brake fade is caused by a buildup of heat in the braking surfaces and the subsequent changes and reactions in the brake system components and can be experienced with both drum brakes and disc brakes. Brake fade occurs most often during high […]
