Question - Express Deflection & Shear Stress
From the relation , obtain the equations which express deflection and shear stress for a close coil helical spring carrying a load W. If the spring is made of 12.5 mm diameter steel wire and has 10 coils at a mean diameter 250 mm, find:
a) Its deflection at the free end;
b) The shear stress produced in the wire when the spring carries a load of 175N .
{take the modulus of rigidity as 80GN/m2 }
Solution:
a) The diagram for the analysis of a spring is like in the figure below:
The deflection of a spring is caused by the torsion of its ...
