The cross section of a bearing block is shown in the figure by the shaded area. Calculate the moment of inertia of the section about its base a-a. Assume b = 19 in., h=5 in., r = 3 in, R=7in. Answer: logi b R in.4 h

The cross section of a bearing block is shown in the figure by the shaded area. Calculate the moment of inertia of the section about its base a-a. Assume b = 29 in., h = 7 in., r = 4 in, R = 8 in. a Answer: la-ai r b R in.4 h

Determine the principal moments of inertia for the beam’s cross-sectionalthe area is shown in Figure with respect to an axis passing through the centroid C.

1. Find the moment of inertia about an axis perpendicular to the page and passing through the pin at O. (We'll often just say, about O in the context of this class.) The plate has a thickness of 15 mm, and is made of steel with a density of 7900 kg/m². 150 mm- 1.40 m 1.40 m
