A screw jack mechanism is to be incorporated into the machine as part of a levelling system. The jack has a thread diameter of 45 mm and a thread pitch of 6 mm with a coefficient of friction of 0.2. The bed mass is 500 kg and if a handle with a radius of 400 mm is used to apply the effort, calculate the efficiency and effort to raise and lower the load.
