Respuesta :
The spring to a length of 125 mm is most nearly is F = 2504 N .
What is spring constant?
The spring stiffness is quantified by the spring constant, or k. For various springs and materials, it varies. The stiffer the spring is and the harder it is to stretch, the bigger the spring constant.
For an elastic spring, we know that F = k x where F = force required, k = spring constant and x = compression or elongation
Here, k = 38.525 N/mm and x = 190 mm ==> F = 2504 N .
