Calculate the horizontal and vertical components of the mass. If the shaft rotating at 200RPM, determine the force excreted on the shaft.
Ashaft rotating at 500RPM carries masses of A = 3kg, B = 4kg and C = 2kg at distances of 0.9m, 0.7m, and 1.7m from the shaft respectively. The angles of A, B, and C respect to horizontal are 40o, 130o, and 290o respectively.
In an Epicyclic gearbox, the Annulus gear “A” is fixed and the input shaft is connected to the Sun gear “S” which rotates at 1800RPM. The Sun gear has 60 teeth and there are three planet gears “P”. The gear ratio between the Sun gear and Planet gear is 2:1.The input power is 45kW and the efficiency is 85%. Sketch a simple arrangement and calculate:
Pass: All questions in section A (including all parts) must be attempted and answered. The assessment criteria and the learning outcomes for Pass grade must be met and fundamental understanding must be demonstrated on this assignment.
Merit: All questions in section A (including all parts) and question B7 in section B must be answered with reasonable accuracy and with no major errors. A neat presentation and good communication of assignment is essential. The assessment criteria for Pass and Merit grade must be met and knowledge and understanding must be demonstrated on this assignment.
Distinction: All questionsin section A and section B (B7 & B8) must be answered fully correct with no errors. All the criteria for Pass, Merit and Distinction must be met. A neat presentation of assignment including any references/ bibliography is essential. All the answers in section B must be synthesised and clearly justified. All the SI units must be clearlyshown in front of calculations, showing full understanding on this
