Illustrate the location of the centroids and write down the formulas for areas and moment of inertia of the following basic shapes: 1. Circle 2. Half circle

Find the moment inertia of the area about the x-axis for the shaded region. y A 10 in 3 in 3 in 9 in 3 in X

COMPLETE SOLUTION:

Determine the moments of inertia about the y-axis of the circular area without and with the central square hole.     0.785 R4, 0.613 R4     0.875 R4, 0.702 R4     0.578 R4, 0.316 R4     0.758 R4, 0.720 R4
