Consider a ladder used by a construction worker as shown below. The worker weight plus his tools is estimated to be 200 lb at mid-height. The ladder is supported at points A and B, developing reactions as shown in the free-body diagram. Assuming that reaction forces RAx and RBx develop magnitudes of 50 lb each and RAy=200 lb, determine MA, MB and MC.
