A la maqueta del taller en tenim dues rodes dentades, com es pot veure a la foto, una petita i blava amb 48 dents i una gran i vermella amb 96 dents. La manovella actua sobre la roda petita, que és la conductora. La roda gran és la conduïda.
1-Si feu girar la roda petita 2 voltes, quantes voltes farà la roda gran? Calculeu la relació de transmissió.
2- Si col·loquem un motor a la manovella de la roda petita que gira a 50 rpm, a quina velocitat girarà la roda gran?
3-El sistema és multiplicador o reductor?
4-En quin sentit gira la roda vermella en relació a la blava? Raoneu

The reset circuit used on the four 3-bit counters analyzed in this activity reset the counts to zero (000). it makes sense for the up-counters to start at zero (000), but the down-counters should start at seven (111). what would you need to change so that the 3-bit binary down counter with j/k flip-flops you just created would reset to seven (111)?

Write a program called assignment3 (saved in a file assignment3.java) that computes the greatest common divisor of two given integers. one of the oldest numerical algorithms was described by the greek mathematician, euclid, in 300 b.c. it is a simple but very e↵ective algorithm that computes the greatest common divisor of two given integers. for instance, given integers 24 and 18, the greatest common divisor is 6, because 6 is the largest integer that divides evenly into both 24 and 18. we will denote the greatest common divisor of x and y as gcd(x, y). the algorithm is based on the clever idea that the gcd(x, y) = gcd(x ! y, y) if x > = y and gcd(x, y) = gcd(x, y ! x) if x < y. the algorithm consists of a series of steps (loop iterations) where the “larger” integer is replaced by the di↵erence of the larger and smaller integer. this continues until the two values are equal. that is then the gcd.
