A uniform, 307.81-N rod is 11.65 n long carries a 257.98-N at its right end and an unknown weight W toward the left end as shown below. W When W is placed 4.18 cm from the left end of the rod, the system just balances horizontally when the fulcrum is located 4.42 cm from the right end. What is the magnitude (N.m) of the torque due to the unknown weight W? (Hint: Make sure t consider the direction of each torques when adding them). Note: Write your answers with 3 digits after the decimal point.
