What does a refrigeration cycle do? The purpose of the refrigeration cycle is to remove the heat in a given area and reject it outside. Less heat means a colder room! What is the difference between heat engine and heat pump? A heat engine is a device that absorbs heat (Q) and uses it […]

What are some other examples of where crank and sliders might be used in the real world?
What are some other examples of where crank and sliders might be used in the real world? Uses. An electric motor driven crank and slider mechanism with a reciprocating motion output can be used as: the basis of a testing device for: testing furniture drawer slides by repeatedly opening and closing drawers, tens of thousands […]

How far behind someone should you drive? two seconds What is required before securing the car? You begin by stopping the vehicle, set your parking brake, then place the gear selector in park, turn off accessories, turn off ignition and remove key, remove any occupant restraint such as seat belt and valuables from sight, check […]
How does heat treatment affect yield strength?
How does heat treatment affect yield strength? The heat treatment develops hardness, softness, and improves the mechanical properties such as tensile strength, yield strength, ductility, corrosion resistance and creep rupture. These processes also help to improve machining effect, and make them versatile. Does Young’s modulus change with heat treatment? Since the Young modulus is related […]
What is human-computer interaction and why is it important?
What is human-computer interaction and why is it important? Human-computer interaction (HCI) is a multidisciplinary subject that focuses on computer design and user experience. It brings together expertise from computer science, cognitive psychology, behavioural science, and design to understand and facilitate better interactions between users and machines. How human-computer interaction affects the society today? The […]

What is conjugate depth in hydraulic jump?
What is conjugate depth in hydraulic jump? In fluid dynamics, the conjugate depths refer to the depth (y1) upstream and the depth (y2) downstream of the hydraulic jump whose momentum fluxes are equal for a given discharge (volume flux) q. The depth upstream of a hydraulic jump is always supercritical. Why momentum equation is used […]
What process results in an increase of entropy?
What process results in an increase of entropy? Increasing the number of molecules in a system also increases the number of microstates, as now there are more possible arrangements of the molecules. Therefore, any change that results in a higher temperature, more molecules, or a larger volume yields an increase in entropy. What are the […]
What happened to farmers in the 1930s?
What happened to farmers in the 1930s? When prices fell they tried to produce even more to pay their debts, taxes and living expenses. In the early 1930s prices dropped so low that many farmers went bankrupt and lost their farms. Some farmers became angry and wanted the government to step in to keep farm […]
