Question
All parts!
A long thin rod of length L and mass M is connected to a hoop of mass M and radius L/2 to form a spoked wheel as shown in the figure below. The wheel is mounted to a fixed axle (frictionless) and can spin about an axis through the center of the wheel and perpendicular to plane of the wheel. Several turns of a light rope are wrapped around the wheel and a mass M is attached to the rope. Use this information to answer the next 3 questions.
1. What is the moment of inertia of the wheel about the rotation axis?
(ML^2)/2
(ML^2/6)
(ML^2/4)
(ML^2)/12
(ML^2)/3
(3ML^2)/20
2. The mass is released from rest and falls downward. What is the tension in the rope as the mass falls?
T = (Mg)/4
T = (Mg)/2
T = (2Mg)/3
T = (2Mg)/5
T = (4Mg)/7
T = (3Mg)/8
3. What is the
a = (5g)/(4L)
a = (6g)/(5L)
a = g/L
a = (6g)/(7L)
a = (3g)/(2L)
a = (2g)/(3L)
