Finding stress and elongation in piston

AI Thread Summary
To determine stress and elongation in a piston, it's essential to understand the relationship between pressure, force, and area, expressed as Pressure = F/A. Given a specific pressure and area, the force applied to the rod can be calculated using this formula. The discussion emphasizes the need to find the force acting on the rod to analyze stress effectively. Understanding these relationships is crucial for evaluating the mechanical behavior of the piston under load. Accurate calculations of force will lead to better insights into stress and elongation in the piston system.

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.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
