- In the image below, suppose we place 0.8 kg a distance of 6cm to the left-hand-side of the fulcrum. How much mass would we have to place at a distance of 78 cm to bring system to equilibrium? Pretend the beam itself is massless. Give your answer in units of grams. Do not explicitly include units in your answer, however (include number only). Including units (like g) will result in the question being scored wrong. mleft Teft Fleft =mleftg fright Fright = mright SMREThe leg and cast in the figure below weigh 250 N, with the center of mass as indicated by the blue arrow in the diagram. The counterbalance wi weighs 110 N.
