Question

10. Use 0 = 0 + a 1 and 0 = 0, +01+iar to derive 0 = 0 +2a (0-0) [5 points) 11. A flywheel of radius 3.40 cm is accelerated from rest at a rate 15.6 rad/s? to reach a final angular speed of 3000 rpm. (a) What is the tangential acceleration of a point on the rim of the wheel during this spin-up process? (b) What is the radial acceleration of this point when the flywheel is spinning at full speed? (c) Through what distance does a point on the rim move through the spin-up process? (6 points)

Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking ..

VAM series R=3.4cm, Wiro Wp = 3000 Y PM= 3000x2 – 314.159 x= 15.6 radlich a) q=2. R= 15.6*3.4 x 8) = 0.5304 wher? And 16 a = w XR = ( 314.159) ²x 3.4x12² = 3355.659 mhec?) C) w? = W;²+200 (314-159) = 0 +2x15.640 =) 0 = 3163.3294 radian. Distance toarelled (s) = ( x ) = 3163.2294x 3.4x17 ( for at radian distance = 107.553m And travelled is 27 meter)!
