Accelerates from test to 500 RPM IN 2 seconds. Determine the Tangential acceleration of one of the point tipsExplanation / Answer
As
alpha = (wf - wi) / t
As wf = 3350 rpm = 350.8 rad/s
wi = 0
t = 5 s
Then
alpha = 70.16 rad/s^2 [ANSWER]
*******************
As
alpha = (wf - wi) / t
As wf = 500 rpm = 52.36 rad/s
wi = 0
t = 2 s
Then
alpha = 26.18 rad/s^2
As
atan = alpha R
and R = 10 in / 2 = 5 in,
atan = 130.9 in/s^2 or 3.3248 m/s^2 [ANSWER]
