What are the potential hazards relating to materials handling injuries OSHA? The hazards associated with materials handling include: • the improper use of equipment, • the accumulation of materials and clutter, • unsafe conditions of materials and containers, • toxic and flammable materials, • the weight of materials being handled, • binding ties or other […]
What happens when a positive charge meets a neutral object?
What happens when a positive charge meets a neutral object? Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other. When a positively charged conductor touches […]
What is a certified professional engineer?
What is a certified professional engineer? What is a PE license? A Professional Engineering license is a certification that demonstrates an engineer’s adherence to a higher level of standards. Prior to 1907, proof of skill and proficiency was not required for individuals to work as engineers, thus putting public welfare, health, and safety at risk. […]
CAN 1000 amps kill you?
CAN 1000 amps kill you? Any electrical device used on a house wiring circuit can, under certain conditions, transmit a fatal current. While any amount of current over 10 milliamps (0.01 amp) is capable of producing painful to severe shock, currents between 100 and 200 mA (0.1 to 0.2 amp) are lethal. How many volts […]
How do polymers degrade from UV attack?
How do polymers degrade from UV attack? UV radiation causes photooxidative degradation which results in breaking of the polymer chains, produces radicals and reduces the molecular weight, causing deterioration of mechanical properties and leading to useless materials, after an unpredictable time. What is oxidative degradation of polymers? Oxidative degradation involves the disintegration of macromolecules by […]
What is quality control definition?
What is quality control definition? Quality control involves testing of units and determining if they are within the specifications for the final product. The purpose of the testing is to determine any needs for corrective actions in the manufacturing process. Good quality control helps companies meet consumer demands for better products. What does TQM mean? […]
How the capacity of hydraulic accumulator is calculated?
How the capacity of hydraulic accumulator is calculated? Hydraulic Accumulators operate on the principles of Boyle’s Law of Gases! The basic relationship between the pressure and the volume of gas is expressed by the equation: P1V1n= P2V2n, where P1 and P2 are the initial and final gas pressures and V1 and V2 are the corresponding […]

When current in a circuit reverses its direction in a regular pattern it is called? Electricity and Magnetism Question Answer Current that reverses direction in a regular pattern is called ____. alternating current The […]
How do you calculate the number of tubes in tube and shell heat exchanger?
What is the name of the coupling?
What is the name of the coupling? A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other. How do you classify a coupling? However there are two main types […]
