The control linkage for a machine consists of two L2 steel rods BE and FG , each with a diameter of 1 in. If a device at G causes the end G to freeze up and become pin-connected, determine the maximum horizontal force P that can be applied to the handle without causing either of the two rods to buckle. The members are pin-connected at A , B , D , E , and F .
