Can somebody help me to solve this problem and guide? I need to calculate minimum force (F) (Newtons or kilograms) is required to pull down object (K1) to (K2), or to hold it in position. Angle between (K1) and (K2) = 50 degrees. Using mounting points (P1) and (P2). (K1) mass = 3.5 ton, (A) Length = 9 meters, (B) Height = 3.5 meters. Mounting points (P1) and (P3 is on a hinge) distance from center = 75centimeters, (C) = 1.3 meters in total. Height from point (P1) to (P2) is 1.7 meters.
