Q1:- A pair of spur gears with 12 and 20 teeth are made with an involute form, pressure angle 20° and 5 mm module. (a) What should be the maximum addendum for the 20-tooth gear such that the interference is just avoided? (b) Using the addendum for the gear, find the addendum of the pinion which will result in a contact ratio of 1.4.

Please help me answer this questions from no.s 8 to 14 with figure. Plsif u can answer it all pls help me I promise to give high feed back
For the gear train below, th numbers of teeth for individual gears are 12 9gear #1), Gear 18 (gear #2), 14 (gear #3), and 18(gear #4), To obtain a counter-clockwise rotation of 1500 rpm for the output gear(#4). What should be the rotation speed of the input gear (#1) and in which directions should the input gear rotate
answer of these three boxes
In the planetary gear train shown in below figure, Gear A is the driver and gears B and D are compounded.Gears E and C are internal gears with C as the fixed gear.Number of teeth on gears are TA-20;TB-60; Tc-140;TD-40;,TG-120. If the drive gears rotates at 720rpm CCW when seen from the right, find out the speed at which driven gear rotates C140 120 Output D 40 60 20 Input
