What is the hierarchy of control measures? The hierarchy of control is a system for controlling risks in the workplace. Eliminating the hazard and risk is the highest level of control in the hierarchy, followed by reducing the risk through substitution, isolation and engineering controls, then reducing the risk through administrative controls. What are the […]

What are the parts of a bill of materials? Every line of the bill of materials (BOM) includes the product code, part name, part number, part revision, description, quantity, unit of measure, size, length, weight, and specifications or features of the product. The engineering BOM is often organized by engineers based on a computer-aided design […]

How do you measure viscosity using a viscometer? BACKGROUND Ostwald viscometer is use to determine viscosity of Newtonian fluid. η1 can be determine using following equation. η1=ʆ1t1/ ʆ2t2 X η2 ʆ1=Density of unknown liquid. t1 =Time of flow of unknown liquid. ʆ2 =Density of standard liquid. t2 =Time of flow of standard liquid. η2=Viscosity of […]

What is the function of a power source in an electrical circuit? A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. Why are […]

Which of the following is the best reason for rapid prototyping? Rapid Prototyping helps designers present new concepts to board members, clients or investors so that they can understand and approve a development or product. This visualisation can also allows designers to gain ready feedback from customers and clients based on an actual physical product […]

The following are some of the things that you will notice when it is time to have your fuel injector O-rings replaced: There is a noticeable fuel leak from where the […]

How do you calculate specific volume of water? Specific Volume Formulas ν = V / m where V is volume and m is mass. ν = 1 /ρ = ρ-1 where ρ is density. ν = RT / PM = RT / P where R is the ideal gas constant, T is temperature, P is […]

Which is an example of an indirect measurement tool? With indirect measurements, the dimensions are measured using measuring instruments such as dial gauges that look at the difference between targets and reference devices such as gauge blocks and ring gauges. What is direct and indirect measurement? ‘Direct measurement’ refers to measuring exactly the thing that […]
