Grade Summary Potential Subreiscieas 100 Anempts remainingExplanation / Answer
Icm = m L^2 / 12 = 0.785 x 1^2 / 12
Icm = 0.0654 kg m^2
from parallel axis theorem,
I = Icm + m x^2
(A) x = 50 - 50 = 0
I = I cm = 0.0654 kg m^2
(B) x = 50 - 0 =50 cm = 0.50 m
I = (0.0654) + (0.785 x 0.5^2)
I = 0.262 kg m^2
(C) x = 0.50 - 0.25 = 0.25 m
I = 0.114 kg m^2
(D) x = 0.95 - 0.50 = 0.45
I = 0.224 kg m^2
(E) I = m L^2 / 12 + m (L/2 - d)^2
(F) I = 0.785 (0.914^2)/12 + 0.785 (0.914/2 - 0.50)^2
{ 1 yard = 0.914 m }
I = 0.0561 kg m^2
