MHB Integration Application: Find the force on each end of the cylinder

Click For Summary
To find the force on each end of a horizontally positioned cylinder filled halfway with tar, first calculate the volume of the tar using the cylinder's dimensions. The volume of the tar is 2m in diameter and 1m in height, resulting in a volume of approximately 3.14 m^3. With a density of 920 kg/m^3, the mass of the tar is 2,888 kg, leading to a weight of about 28,308 N when multiplied by the acceleration due to gravity (9.8 m/s^2). The force on each end of the cylinder is equal to the weight of the tar divided by two, resulting in approximately 14,154 N per end. This approach highlights the importance of understanding fluid dynamics and pressure distribution in cylindrical containers.

A cylinder shaped container of tar has a diameter of 2m. If it is half full of tar with a density of 920 kg/(m^3) and is on it's side, find the force on each end.

Helpful hints:
920 kg per m^3 is the mass density not the weight density. Take g= 9.8 m/ sec^2Please assist. I'm not sure at all how to approach this or what relationships to use.​

I would be interested in seeing your solution. Normally the problems involving cylinders and the density of a material within that cylinder involve calculating the work done by pumping out a certain amount.

Thread 'Problem with calculating projections of curl using rotation of contour'

Hello! I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem. Given: ##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0## ##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1## ##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0## I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
