Figure 1. The maximum extension of spring (ymax = 8.3 mm), the dynamic load varies from 250 N at the low position and 400 N at the high position. The diameter of the circular cam is 200 mm rotates off center with an eccentricity of 25 mm and operates the roller follower that is carried by the arm. The speed of the cam is 200 rpm. Design choices, (C= 140), shear modulus G= 80 GPa, A227 as a material for the spring, Wire endurance limit Sew = 310 MPa, factor of safety for spring body is 1.5. The spring ends are standard. a. Check the initial tension in the spring and compart it with minimum load. b. Determine the physical parameters of the spring. c. Check the surging of spring 200 mm- 100 mm Spring 25 mm
