3. The automobile bumper jack shown at Fig. 3 is subjected to a 4000 N downward load. Starting with a free-body diagram of BCD, determine the force supported by the roller C. Note that roller B does not contact the vertical column. [ Ans : 6470 NJ. Fig. 3 Fig. 4 150 mm 150 mm 400 mm -- 4000 N 100 mm - 700 mm 240 mm 300 mm 00 375 60 D - 1000 mm - 4. The car hoist shown in Fig. 4 allows the car to be driven onto the platform, after which the rear wheels are raised. If the loading from both rear wheels is 6 kN, determine the force in the hydraulic cylinder AB. Neglect the weight of the platform itself. Component BCD is a right-angled bell crank pinned to the ramp at C. [ Ans : 15.87 kNJ.
