Task 2.2 Determine dynamic effects of circular motion

A)

A 15kg wheel with a radius of 250mm accelerates from rest to

2500RPM in 20 seconds. Find the following at a time of 10

seconds:

3333

the angular velocity,

the angular acceleration

the tangential velocity on the rim of the wheel

the centripetal acceleration and centripetal force

the tangential acceleration/nB)

i) A wheel of mass 200kg and radius of gyration 0.8m, accelerates uniformly at

3.8 rad/s². Find the torque required to produce this acceleration.

ii) If the wheel accelerates from rest for 6s and then runs at constant velocity, calculate the

power required during the constant velocity period.
