Hydrostatic force on a plane surface

Click For Summary
SUMMARY

The discussion focuses on the derivation of the width of the integral strip for calculating hydrostatic force on a plane surface. The formula provided is w(s) = b(s - s1)/L, where 'b' represents the base width, 's' is the variable height, 's1' is the initial height, and 'L' is the total height of the triangular lamina. The solution involves using the property of similar triangles to establish the relationship between the variables. This method effectively clarifies the calculation of hydrostatic forces on plane surfaces.

PREREQUISITES
  • Understanding of hydrostatic pressure principles
  • Familiarity with integral calculus

i have this example of a hydrostatic force on a plane surface.

what i don't understand is how the width of the integral strip is derived

it says w(s)=b(s-s1)/L i don't understand how this comes about?

would be really greatful if anyone could direct me i can't find anything on triangular lamina double integration :S

cheers!

just draw a perpendicular from the vertex on the base and then use the property of similar triangles.
w/b=S-s1/L
 
great thanks for that
 

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
