How do you derive the deflection of a beam? Assuming that the deflection of the beam is sufficiently small, we can neglect the first derivative y′. Then the differential equation of the elastic line can be written as follows: y′′=M(x)EIord2ydx2=M(x)EI. The bending moment M(x) can be expressed in terms of the known external load q(x) […]
What is considered a kickback?
What is considered a kickback? A kickback is an illegal payment intended as compensation for preferential treatment or any other type of improper services received. The kickback may be money, a gift, credit, or anything of value. Kickbacks are often referred to as a type of bribery. How do you identify a kickback? Most kickback […]
What factors influence the glass transition temperature of a polymer?
What factors influence the glass transition temperature of a polymer? Pressure and free volume. Increase in pressure of surrounding leads to decrease in free volume and ultimately high Tg. Other factors like branching, alkyl chain length, bond interaction, flexibility of polymer chain, film thickness etc. also have significant impact on glass transition temperature of polymers. […]
What is machine breakdown?
What is machine breakdown? In its simplest form, an equipment breakdown covers a piece of machinery when it stops working due to an internal malfunction or a broken part(s), requiring the repair or replacement of that equipment. What is machine breakdown analysis? This team-based approach to maintenance improvement looks at the failure on a physical […]

How do non azeotropic refrigerant blends leak from a system?
How do non azeotropic refrigerant blends leak from a system? How do non-azeotropic refrigerants leak from a system? In uneven amounts, due to different pressures. Sets a schedule for the phase out of CFC/HCFC production, prohibits venting of refrigerants, authorizes the EPA to set standards for recovery of refrigerants. Which human health effects increases from […]
What type of system energy is related to the molecular structure of a system?
What type of system energy is related to the molecular structure of a system? Internal energy is related to the molecular structure and the degree of molecular activity and it may be viewed as the sum of the kinetic and potential energies of molecules. kinetic energy of molecules, and it is also called the sensible […]

What is the standard text height for AutoCAD?
What is the standard text height for AutoCAD? The majority of text in a typical Autocad drawing with decimal-based units should have a plotted height of 0.08” (L80) or 0.10” (L100). Engineering and surveying disciplines assign special names to text styles according to their plotted height. What is the minimum text height for full size […]
