Chapter 9, Problem 85P

The coordinates of the centroid of the line are = 332 and = 102. Use the first Pappus Guldinus theorem to determine the area, in m2, of the surface of revolution obtained by revolving the line about the x-axis. The coordinates of the centroid of the area between the x-axis and the line in Question 9 are = 357 and = 74.1. Use the second Pappus Guldinus theorem to determine the volume obtained, in m3, by revolving the area about the x-axis.

Determine the pressure of inside the right circular cylinder whose radius is 0.134 m and height of 0.318 m containing 50 lbs of benzene at 600F.

3) A hemisphere of diameter 60 mm is placed on the top of a cylinder, whose diameter is also 60 mm. The height of the cylinder is 75 mm. Find the common CG of the composite body. Hence CG of the given solid is at (0 mm, 47.6 mm, 0 mm)

Use the theorems of Pappus and Guldinus to solve the fol- lowing problems. Determine the volume V of the solid body generated by re- volving The shaded area of Fig. through an angle of 360° about the x-axis. 100 150 mm mm 150 mm 150 mm 150 mm 100 mm

I got 699789.76 mm^3 and it's incorrect. How do I find the volume?

Set up and evaluate the integral that gives the volume of the solid formed by revolving the region about thexaxis. Step 1 From the figure consider the representative rectangle. The radius of the solid of revolution obtained by revolving the rectangle about the xacis is R(X) -y9- To find the volume of a solid of revolution with the-Select mathod, use the horizontal axis of revolution.

3.94 The aluminum cylinder is attached to the steel hemisphere. Find the height h of the cylinder for which the center of gravity of the assembly is at G. Use =0.283lb/in.3 for steel and =0.096lb/in.3 for aluminum.

A solid of revolution is formed by rotating the plane area about the axis AB. Compute the volume and the surface area of the solid.
