Part CD has negligible weight. It is pinned at Point C, connected to a roller at D, and touching the spring. The easiest method to solve for the reaction at Point D is : 1.3m 0.7m 0.238m 0.2m 0.2m 0.75m 1.4m 1.432m spring pinned at pt B. and compressed 0.4m. k=500N/m D 40 O sum forces in the X direction (use only this equation to solve for the reaction at D) O sum forces in the Y direction (use only this equation to solve for the reaction at D) O sum moments about Point D (use only this equation to solve for the reaction at D) sum moments about Point C (use only this equation to solve for the reaction at D) O it is not possible to solve for the reaction at Point D with only one equation
