There are two connected spur gears attached to a fixed board at points A and B. The assumptions of the system are that the pinion (part 1) is driven at an angular velocity of ω1, and the gear (part 2) is then constrained to rotate at an angular velocity of ω2.
Please state what the joints are in the system.
Note that the constraint equation between the two gears in the integrated orientation form is:
Where θ1 and θ2 are the gear orientations for gears 1 and 2, α1 and α2 are the gear radii for gears 1 and 2, and C1 and C2 are constants.
Using your knowledge of computational kinematics determine the following:
If you cannot do the mathematics, then please explain what you believe is the procedure to calculate each variable.
The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. explain how these thermometers can be used to estimate the amount of water vapour in the air.
A pump station has been designed to lift water out of a 6 metre deep pit (vented to atmosphere) via a centrifigual pump mounted at ground level. Calculate the Net Positive Suction Head (NPSH) for the system ?
Important information about Overall Heat Transfer Coefficient A copper sphere of internal diameter 2 m and wall thickness 40 mm is insulated with 75 mm of expanded polystyrene
8 x product engineering and design review (week 2 – 12), ~3 pages per item which must contain a brief description of the product then delve into concepts such as materials selection, manufacturing methods, life cycle analysis, recyclability and overa..
Consider the 2.0micrometer long GaAs device where the E-field is 5kV/cm and Mn*=.067M0. Calculate the transit time of an electron through the device if the mobility is 8000 cm^2V-s.
this would provide you with a set of Reynolds numbers. Next, using the integral method, determine the velocity profiles within the boundary layer to be followed by determination of the heat transfer coefficient values for your selected Reynolds numbe..
