eith Walker, nt-Patterson AFB, 937.255.9217 (voice 937.512.2183 (MET Office) -25%, Final - 25%, Moments and Couples 3-15. A large rock has forces acting on it as shown in Figure P3-15. Determine the moment about point A. 200 lb 600 lb 3 1' 20 FIGURE P3-15 1200 lb 5 31.5 3-16. The spring at A in Figure P3-16 opposes the moment about B due to the 500-N force. Deter- mine the moment about B due to the 500-N force. If the spring has an equal and opposite moment about B, determine the spring tension. 500 N 15⁰ 25 GURE P3-16 17. For the forklift truck shown in Figure P3-17 determine (a) the moment about A due to the tw weights shown and (b) the moment about B due to the two weights shown. Forklift Load weight 4000 lb weight = 1500 lb 2 4
