Two gears are calibrated so that the smaller gear dives the larger gear. For each rotation of the smaller gear, how many degrees will the larger gear rotate?

Question

Two gears are calibrated so that the smaller gear drives the larger gear. For each roation of the smaller gear, how many degrees will the larger gear rotate?

radius of the smaller gear= 2cm

radius of the larger gear=5cm

Answer 1

Smaller gear circumference is 2pi * r =4pi

Langer gear circumference is 2pi * r = 10pi

If evrthg is ideal when smaller gear rotates 4pi so does larger gear.

So larger gear rotated 4pi which is 40% of 10pi.

So in degrees it rotated 40% of 360 degrees which jd 144 degrees
