Chapter 9, Problem 75P

Half the cross section of the steel housing is shown in the figure. There are six 10-mm-diameter bolt holes around its rim. The density of steel is 8.10 Mg/m3 . The housing is a full circular part. Determine its mass.

Determine the x and y component of the center of gravity of all the components. If the heights of the components are given as z1 = 1.90mm, z2 = 0.500mm, and z3 = 0.150mm, determine the z component of the center of gravity of all the components.

The cube is 12 inches in dimensions. The cylindrical hole is 5 inches in diameter and 6 inches drilled in it. The hole is filled by a metal pin with γm= 50-lb. The wood γw= 50-lb. Locate the center of gravity of the body.
