Homework Statement
Hi
We have a project on third semester where we should calculate different things on a 4 stroke engine.
My assignment is to prove that the bolts between the cylinder and the cylinder head has the right size.
The following information is given:
Maximum pressure in cylinder: 59.5 bar
Tightening torque: 25 Nm
Bolt: M8x125 DIN EN ISO 4014
and all the dimensions on the cylinder and the cylinder head
So far, I've calculated the stiffness of the bolts and the cylinder (assuming that the cylinder is a pipe)
I want to calculate the deflection and then draw a deflection diagram but I'm stuck
Homework Equations
k_b = F_b / δ_b , where k_b = stiffness, F_b = the load and δ_b = displacement
The Attempt at a Solution
I know that the maximum force in the cylinder can be defined by F_max = p_max * A_max
but should I use that force to find the deflection?
or maybe the force ratio * F_max ??
