How do you determine breaking strength? Method of finding the Breaking Strength (B.S) is to divide the square of the diameter of the rope in millimetres by 200. Method of finding the Safe Working Load (S.W.L) is to divide the Breaking Strength by factor of safety. What is the difference between breaking strength and tensile […]

Do volts or amps hurt you? In fact, its voltage will be high enough to overcome your skin’s resistance. It can pass through your skin into your blood vessels. If the level of amps is high enough, it can do some serious damage to your body tissues. It could even kill you! How many volts […]

What factors determine the voltage rating of a capacitor? Three factors determine the capacitance of a capacitor: The area of the plates. The distance between the plates. The type of dielectric used. What is breakdown voltage of capacitor? Breakdown voltage of a Capacitor Above that electric field strength , the material conducts electric charges and […]

What is the minimum sampling rate? The minimum sampling rate is often called the Nyquist rate. For example, the minimum sampling rate for a telephone speech signal (assumed low-pass filtered at 4 kHz) should be 8 KHz (or 8000 samples per second), while the minimum sampling rate for an audio CD signal with frequencies up […]

What is the relation between compression ratio and the efficiency of the Otto cycle? Explanation: This is the expression for efficiency of Otto cycle and rk=compression ratio=Vmax/Vmin. Why is Otto cycle more efficient? 3. 6 Diesel Cycle. Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be […]

Is it bad if you drive with your emergency brake on? When you drive with the parking brake even partially on for several miles, it’s possible to warp a drum or disc. Or if the brakes get really overheated, you can even cause the lining’s adhesive to fail, and have the linings crack or even […]

How do you calculate the half life of strontium-90? For example, the half-life of strontium-90 is 28.8 years. If you start with 10 grams of 90Sr and wait 28.8 years, you’ll have 5 grams left of 90Sr. If another 28.8 years go by, 2.5 grams will remain. What’s the half life of strontium-90? 29 years […]

What is the term for the increasing interconnectedness of economies around the world? Globalization. the increasing interconnectedness of different parts of the world through common processes of economic, environmental, political, technological, social and cultural change. What effect does increasing economic interdependence have on the countries of the world? In this context, one positive effect of […]

What is condition monitoring techniques? Condition monitoring to help prevent machine failure ​Condition monitoring is the process of monitoring machinery – by vibration, temperature or other methods – to identify a significant change which could indicate a developing fault. It is a major component of predictive maintenance. What is condition monitoring in the field of […]

What type of electrode is used by the gas metal arc welding process? Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them […]
