What is the difference between yield stress and ultimate stress? Yield stress is the stress at which that the material deforms permanently, ultimate tensile stress is the stress at which it breaks. What happens to a material when it undergoes stress that exceeds its strength? For stresses beyond the elastic limit, a material exhibits plastic […]
Should I record 48KHz or 96KHz?
Should I record 48KHz or 96KHz? Recording: For pop music stick to 48 kHz, but 44.1 kHz is acceptable. For audiophile music or sound design you may prefer 96 kHz. Mixing: Mix sessions should remain at the sample rate of the recording. You will not improve the sound of a project by upsampling a session […]

Is Titanium better than tungsten?
Is Titanium better than tungsten? Hardness – Both titanium and tungsten carbide are considerably harder than precious metals like gold and platinum. However, tungsten carbide is one of the hardest materials in existence and substantially harder than titanium, registering a 9 on the Mohs scale of mineral hardness (compared to titanium’s score of 6). What […]
What are the 4 types of fire?
What are the 4 types of fire? Classes of fire Class A – fires involving solid materials such as wood, paper or textiles. Class B – fires involving flammable liquids such as petrol, diesel or oils. Class C – fires involving gases. Class D – fires involving metals. Class E – fires involving live electrical […]
What component can mask internal engine oil leaks?
What component can mask internal engine oil leaks? Modem engine run at high internal engine temperatures and are also equipped with very efficient catalytic converters. These can mask internal oil leaks. When was motor oil invented? 1866 What can be used as a tracing powder when checking for small oil leaks? Once the engine is […]
Is lean only for manufacturing?
Is lean only for manufacturing? Lean manufacturing is a body of knowledge used to continuously improve processes and deliver value to customers. It has a lot of overlap with industrial engineering and quality engineering, but it is not only for engineers and it is not only for manufacturing. What are lean practices? Lean is defined […]
Are all new furnaces High Efficiency?
Are all new furnaces High Efficiency? In this type of furnace, 20% of the energy produced by natural gas is expelled as exhaust. High efficiency furnaces offer 90% or more AFUE. These days, 95% AFUE is a common rating among new gas-powered furnaces. So a 95% furnace is more efficient than an 80% furnace. What […]
How is capillary effect affected by the contact angle?
How is capillary effect affected by the contact angle? Capillary action can also be to understood in terms of capillary pressure. Pcap = 2 γlv *cos(θ) / r. From this, we see that the lower the contact angle (the more hydrophilic the pore) the higher the capillary pressure and thus the the stronger the capillary […]
What are the main parts of a clutch assembly?
What are the main parts of a clutch assembly? The modern clutch has four main components: the cover plate (which incorporates a diaphragm spring), the pressure plate, the driven plate, and the release bearing. What parts are included in a clutch kit? Summary. A clutch kit is a selection of parts that are used to […]
