A uniform rod of length 50cm and mass 0.2kg is placed on a fulcrum at a distance of 40cm from the left end of the rod. At what distance from the left end of the rod should a 0.6kg mass be hung to balance the rod?
Added by Teresa C.
Step 1
The moment is calculated as the product of the force and the distance from the fulcrum. The force due to the weight of the rod is distributed evenly along its length, so we can consider it to be acting at the center of the rod, which is 25cm from either end. Show more…

A uniform rod is 2.00 m long and has mass 1.80 kg. A 2.40-kg clamp is attached to the rod. How far should the center of gravity of the clamp be from the left-hand end of the rod in order for the center of gravity of the composite object to be 1.20 m from the left-hand end of the rod?

A uniform rod is 2.00 $\mathrm{m}$ long and has 1.80 $\mathrm{kg} . \mathrm{A}$ $2.40-$ -kg clamp is attached to the rod. How far should the center of gravity of the clamp be from the left-hand end of the rod in order for the center of gravity of the composite object to be 1.20 $\mathrm{m}$ from the left-hand end of the rod?
