Name: _________________________________________ Problem #4 (6 points) The displacement of a spring under an applied force (F) is related to the stiffness of the spring (K) by the equation = K F . The stiffness of a spring is itself a function of its shear modulus (G), the number of coils (N), and geometric properties D and d. N D d G K 3 4 8 = Complete the MATLAB code below so that the spring stiffness is calculated for a series of wire diameters, number of coils, and specific set of coil diameters. G = 1e8 % Shear modulus in Pascals
