Computer Problems C7-115 The mechanism shown in Fig. P7-115 is designed to keep its load level while raising it. A pin on the rim of the 4-ft-diameter pulley fits in a slot on arm A ABC and DE are each 4 ft long, and the packag weighs 80 lb. The mechanism is raised by pulling on the rope, which is wrapped around the pulley BC. Arms e being lifted a. Plot P, the force required to hold the platform as a func- tion of the platform height h (0 shs 5.5 ft) b. Plot A, C, and E-the magnitudes of the pin reaction forces at A, C, and E-as a function of h (0shs 5.5 ft) 40 This side up 3 ft 2 ft Computer Problems C7-115 The mechanism shown in Fig. P7-115 is designed to keep its load level while raising it.
