Question

Problem 10.12

A 62-cm-diameter wheel accelerates uniformly about its center from 130 rpm to 290 rpm rpm in 4.0 s .

Part A

Determine its angular acceleration.

Express your answer using two significant figures.

4.2

rad/s2

Part B

Determine the radial component of the linear acceleration of a point on the edge of the wheel 2.0 s after it has started accelerating.

Express your answer using two significant figures.

Part C

Determine the tangential component of the linear acceleration of a point on the edge of the wheel 2.0 s after it has started accelerating.

Express your answer using two significant figures.

4.2

rad/s2

alpha = 4.188 rad/s^2

ar = w^2 R

w = 130+290/2 = 210rpm = 21.99 rad/sec

ar = 149.919 rad/s^2

at = Rxalpha

at = 1.298 m/s^2
