Question 3(a) A compound gear train consists of 7 gears (1– 7) in total with the number of teeth given inthe table below. Gears 2 and 3 and gears 5 and 6 are a compound gear set. Gear 1 rotates in aclockwise direction.N1 = 45, N2 = 30, N3 = 60, N4 = 20, Ns = 45, N6 = 54, N7= 25i. Briefly sketch and label the gear train. Note a 2D sketch is sufficient and the diametersof the gears are not required at this stage so use your own judgement on sizing but clearlystate any assumptions.ii. Determine the Velocity Ratio and Train Value of the gear Train.iii. If the input speed is 200rev/mins determine the output speed and direction.iv. Determine the speed of gear 4.(b) A 1m long rectangular beam supported at either end is subjected to a 5kN point load in thecentre. Determine the maximum bending and maximum shear stress if the beam is 20mm thickand 200mm wide.

Figure shown below illustrates the gears in a speed-change gearbox used in machine tool applications. By sliding the cluster gears on shafts Band C, nine speed changes can be obtained as shown in Table given below. The problem of the machine tool designer is to select tooth numbers for the various gears (2 to 10) so as to produce a reasonable distribution of speeds for the output shaft. The gears 2, 6 and 9 are having 20, 25 and 50 teeth respectively. The input shaft speed is 450 rpm and the output speed can vary from 137 rpm to 580 rpm depending on the sequence of the gears. If the output speed obtained through the gear sequence 2-5-5-8 is 257 rpm and if the minimum and maximum number of teeth in the gear system are 20 and 50 respectively, (i) Suitable tooth numbers for the remaining gears (3,4,5,7,8 & 10)
