What is the primary duty of a machine tool operator? Machine Operator Responsibilities: Assist in the installation, maintenance, and repair of machinery. Operate tools in order to aid in the manufacturing process. Perform periodic checks on equipment and solve problems as detected. Work with others in order to ensure that equipment is in proper working […]
What is the Kelvin Planck statement of the second law?
What is the Kelvin Planck statement of the second law? The Kelvin–Planck statement (or the Heat Engine Statement) of the second law of thermodynamics states that it is impossible to devise a cyclically operating heat engine, the effect of which is to absorb energy in the form of heat from a single thermal reservoir and […]
What depth are TYRE wear indicators set at?
What depth are TYRE wear indicators set at? 1.6mm Where is the tire wear indicator? Tread wear indicators (“wear bars”) are located at the base of the main grooves and are equally spaced around the tire. The tread wear indicators, which look like narrow strips of smooth rubber across the tread, will appear on the […]
How do you calculate equivalent sound level?
How do you calculate equivalent sound level? The equation to calculate Leq divides the integrated, normalized sound pressure by the duration of interest of the signal. The result is expressed in units of decibels: Leq = equivalent continuous sound pressure level in dB. How do you calculate sound pressure level? Sound pressure level (SPL) is […]
How does heat conduction differ from heat convection?
How does heat conduction differ from heat convection? In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles. What is the difference between conductive heat transfer and convective heat transfer give one example of […]
How do you draw a spur gear?

Draw a circle, then assign its diameter to “Head Diameter”. Adding a Bore (Optional) Extruding the Sketch (Base) Drawing the Gear’s teeth inbetweens. […]
What does cyanide do to the body?
Why is BOD test done for 5 days?
Why is BOD test done for 5 days? The standard oxidation (or incubation) test period for BOD is 5 days at 20 degrees Celsius (°C) (BOD5). The BOD5 value has been used and reported for many applications, most commonly to indicate the effects of sewage and other organic wastes on dissolved oxygen in surface waters […]
What is the difference between accelerometer and vibrometer?
What is the difference between accelerometer and vibrometer? Abstract. The use of accelerometer based measurement techniques for evaluating bridge forced vibrations or to perform bridge modal analysis is well established. On the other hand laser vibrometer systems detect relative displacements as opposed to the absolute measures of accelerometers. What is a multibeam vibrometer? OMS – […]
What is the process of honing?
What is the process of honing? Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish. […]
