The information about the patient bed emergency on an ambulance is number one. What should consider what.The first is to know the strength (Force) act to bed legs on each side to analyze moment (Moment) that act within the structure leg bed. Based on the principle of Newton motion equation Free analysis and Body Diagram position began to change the direction of the leg mobile bed. (Extreme Position), which has 2 positions, including the folding bed legs. Spread your legs and bed position, as shown in Figure 3 due to a position to use high strength to overcome static friction occurs between the various parts of the leg structure bed. Under the hypothesis as follows.The hypothesis in calculating - all the weight down to the legs on each side 86 kg.Heavy weight patients 305 - kg.All the hard 39 bed - Weight kg.Total weight 344 kg - weight- a weight to a hospital bed legs and 4 equal.- leg angle bed 18.79 degrees while folding nursing bed- leg angle 59.42 degrees, while the bed legs extended nursing bedGravitational constant value - 9.81 meters / sec ^ 2.- weight towards the bed legs each leg heavy 344 / 4 = 86 kg.- leg shape bed is a Beam had tons of ambulance- acceleration of the sick bed legs, but side equals 0.- friction coefficient static equals 0.3.- leg hospital beds for patients on an ambulance, long 1 300 cm.
