Two metal disks are taped to a meter stick. The mass of the meter stick is 540.0 g. Disk 1 has a mass of 500.0 g and is located at the 29.0 cm mark. Disk 2 has a mass of 300.0 g and is located at the 76.0 cm mark. At what position along the meter stick should you place a fulcrum so that the entire system (meter stick plus the 2 masses) are balanced?© BrainMass Inc. brainmass.com March 4, 2021, 5:40 pm ad1c9bdddf
Mass of meter stick=540 g
Mass per cm=540/100= 5.4 g/ cm
Let the fulcrum be placed at the x cm mark
500 * (x-29) + (5.4*x)(x/2) 5.4 x is the ...
The solution determines the location of a fulcrum such that the meter stick plus the 2 masses are balanced.
