Finding stress and elongation in piston

Click For Summary
SUMMARY

The discussion centers on calculating the force applied to a piston rod using the relationship between pressure, force, and area, defined by the formula Pressure = F/A. Participants emphasize the need to identify the pressure and area values to determine the force accurately. The conversation highlights the importance of understanding these fundamental concepts in mechanical engineering and fluid dynamics.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Familiarity with the formula Pressure = F/A
  • Basic knowledge of piston mechanics
  • Concept of force and area in engineering contexts
NEXT STEPS
  • Research the application of Pascal's Law in hydraulic systems
  • Explore the calculation of stress and elongation in materials
  • Learn about the properties of different piston materials and their impact on performance
  • Investigate advanced topics in fluid dynamics related to pressure and force
USEFUL FOR

Mechanical engineers, students studying fluid mechanics, and professionals involved in designing hydraulic systems will benefit from this discussion.

Homework Statement
Estimate the stress in the piston rod (6 cm in
diameter) [MPa] and the elongation of the 1 m long piston rod [cm] under these static
condition. Since these are external to the fraction, steel is often used, as in this case.
Relevant Equations
delta(l)=F*l/E*A
E for steel is 200 MPa
A=pi*r^2
I am really just totally stuck. I think you need to find force being applied onto the rod but I cannot figure that out

Right, and you are given a pressure and an area.
