A meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 58.0-gram mass is attached at the 18.0-cm mark, the fulcrum must be moved to the 39.2-cm mark for balance. What is the mass of the meter stick?

A baseball bat balances 72.9 cm from one end. If an 0.525-kg glove is attached to that end, the balance point moves 25.6 cm toward the glove. Calculate the mass of the bat.

A fulcrum is placed under a meter stick at its center of mass at 40 cm. This is the place where the meter stick pivots. A 150 g mass is clamped at the 10 cm mark. An unknown mass is clamped at the 50 cm mark and the system is in equilibrium. Ignoring the mass of the clamps, what is the unknown mass?

A weight of 6 N is located 8 cm from the fulcrum on the beam of a simple balance. What weight should be placed at a point 4 cm from the fulcrum on the opposite side in order to balance the system?
