A load of 2100 N is dropped axially on a closed-coiled helical spring from a height of 240 mm. The spring has 22 coils each of mean diameter 180 mm and wire diameter is 25 mm. If the modulus of rigidity C=84000 N/mm² and amount of compression 8 = 255 mm, what is the maximum shear stress produced in the spring?
