Problem 3:   A helical spring is designed to have a stiffness of 500 N/m. The spring has a wire diameter of 5 mm and an outer diameter of 30 mm. Determine the number of coils required for the spring if the spring index is 6.   Problem 4:   A helical spring is compressed by a force of 100 N, resulting in a compression length of 20 cm. The spring has a wire diameter of 3 mm and a mean coil diameter of 15 cm. Determine the spring constant (stiffness) of the spring.
