Re: Need help urgently would really appreciate any help regarding Angular Velocity
ahh i get it so pi / 3 radans is 60 degrees. i was thinking i had to do something fancy with it
Re: Need help urgently would really appreciate any help regarding Angular Velocity
im confused because i don't have the arc length so i won't be able to work out the angle? the formula for the arc length is angle x pi x r / 180 and to work out the area its s x r / 2
(i) A rotating machine shaft turns through 2100 revolutions in 3 minutes. Determine the average angular velocity, w, of the machine shaft in rad/s.
the answer for this is
2100 x 2 pie = 4200 pie radian
3 mins = 180 seconds
4200 / 180 = 73.3 rad/s
(ii) Determine the area and arc length of the...
