Question A pair of straight teeth spur gears, 200 involute full depth teeth is to transmit 10kW at 200rpm of the pinion. The velocity ratio is 3. The module value is 6mm and the face width is equal to 10 times module value. The number of teeth of pinion is 30 and the material combination factor K is 1.32 N/mm2. The service factor is 0.8 and the deformation factor C =80 N/mm. a) Determine the dynamic load for the pinion ( enter the value in kN) Answer kN b) Determine the wear load for the pinion load ( enter the value in kN) Answer kN c) Is the design satisfactory?. i) Yes, the wear load for the pinion is greater than the dynamic load. ii) Yes, the wear load for the pinion is less than the dynamic load. iii) Yes, the wear load for the pinion is equal to dynamic load.

A pumped fluid distribution system is being designed to deliver 400 gal/min of water to a cooling system in a power generation plant. Use the figure below to make an initial selection of Schedule 40 pipe sizes for the suction and discharge lines for the system. Also, solve for the actual average velocity of flow for each pipe

Consider the quadric surface given by 314 22 – 216 x y - 48 x z + 404 y2 + 72 yz +250 22 = 3025 (a) Express this equation in the form x? Ax = 3025 where A isa symmetric matrix and x = y Enter the matrix A in the box below a ab sina 8 a 12 E aac (b) You are given that the matrix A has eigenvalues 242, 242 and 484. Hence the equation of the surface in terms of its principal exes X, Y and Z can be written as 242 x 2 +242 Y2 + 484 22 = 3025 Enter the shortest distance, in Maple syntax, from the origin to the surface in the box below. Note: Use sqrt command when necessary.

2. A 2-wire d.c. distributor, 500 m long is fed at one of its ends. The cross-sectional area of each conductor is 3-4 cm and the resistivity of copper is 1-7 uNcm. The distributor supplies 200 A at a distance of 300m from the feeding point and 100 A at the terminus. Calculate the voltage at the feeding end if the voltage at the terminus is to be 230 V. [241 V]

Many companies are undergoing server virtualization. This is the concept of putting multiple “virtual” servers onto one physical device. The payoffs can be significant: fewer servers, less electricity, less generated heat, less air conditioning, less infrastructure and administration costs, increased flexibility, less physical presence (that is, smaller server rooms), faster maintenance of servers, and more. There are costs, of course, such as licensing the virtualization software, labour costs in establishing the virtual servers onto a physical device, labour costs in updating tables, and access. But determining the return on investment can be a challenge. Some companies have lost money on server virtualization, while most would say that they have gained a positive return on investment but have not really quantified the results. (a) How might a company really determine the return on investment for server virtualization? (b) Is this a project that a systems analyst might be involved in? Why or why not?

A furniture company produces tables and chairs. The profit on each table is $15 and $5 for each chair. The amount of wood available is enough for at most 25 tables and chairs. They need to produce at least 5 tables but no more than 15 tables. They also need to produce at least 10 chairs but no more than 20 chairs. The company needs to know many of each should be prepared to maximize the profit. How could the variables be defined? Group of answer choices let x equal the number of tables produced. let x equal the number of tables produced and let y equal the number of chairs produced. let x equal the cost of tables produced and let y equal the cost of chairs produced. let x equal the amount of wood needed to produce a chair and Y the amount of wood needed to produce a table
