I am new to the forum. I was calculating the force losses in a seat belt pretensioner. Here is the question.
A cylindrical plastic rod is pushed on one side at a force of 6367.2 N inside a metal tube. Find the energy loss (force loss or final force or output force) due to the compression of the rod.
Given
Initial pressure = 670 bar
Initial force= 6367.2 N
Original length of rod= 177 mm
Changing length of rod = 37.80 mm
Rod material = plastic
Youngs modulus of rod= 1.8 GPa
Inner dia of tube = 11 mm
Dia of rod = 9.6 mm
Please help.
