Problem 3 E B * a b C d 1.15 in 0.44 in 0.82 in 1.88 in 1.72 in A force of P = 20.1 lb is required to pull the stopper (DE). The dimensions of the symetrical stopper-puller device are given in the table above. Determine the internal forces acting on member BCD given in the table below. Also, determine the minimum pin diameter for pin C given that it is made of cast aluminum and has a factor of safety of 5 against fracture Forces: (Denote rightward or upward forces with positive values; leftward or downward forces with negative values) At this point, this body exerts a horizontal force of: and a vertical force of: on this body. The magnitude of the resultant force is: B AB BCD C ECF BCD D stopper D BCD Dpinc F 14.1lb, 10.1lb, 17.3lb -45.5lb, Olb, 45.5lb 31.4lb, -10.1lb, 33.0lb 0.0983in
