2. The figure shows a spring chair. The chair weight is 100 N. The spring free-length is 500 mm, mean diameter is 200 mm, wire diameter is 10 mm and number of turns is 12. The spring wire material is Music wire A228 with modulus of rigidity of 82700 MPa. Calculate the initial deflection of the spring under the chair weight. If a child seats on the chair, calculate his weight to bush the spring to the shut height. Calculate the stresses in the spring at that condition. 8FD'N d'G y = 8FD T = K,- 4C + 2 KB = 4C – 3 C = 00000000ood
