The thin-walled cylindrical can with a spherical dimple weighs 0.2 lb. Determine the force P required to push the can into water to a depth of 8 in. Use =0.036lb/in.3 for water.
The plane region A is submerged in a ï¬‚uid of weight density . The resultant force of the ï¬‚uid pressure on the region is R acting at the point C (called the pressure center) located at the distance h below the surface of the ï¬‚uid. Show that R=Qa and h=Ia/Qa, where Qa and Ia are the first and second moments of A about the axis a-a.
