Unformatted text preview: Set F B = 1610 N and F C = 2400 N. 3. (20 points) Find the moment about point O . 4. (20 points) A machine handle is connected to a shaft at B. Determine the moment produced by the 15 N force about point B . 5. (20 points) The 70-N force acts on the end of the pipe at B . Determine the angles θ (0° < θ < 180°) of the force that will produce maximum and minimum moments about point A . What are the magnitudes of these moments?...
