The rod is 4.3 m long hanging weights 9 kg and 15 kg on ends. Where is the center of the rod (distance from weight 9 kg) to be in balance?

Correct answer:

x =  2.69 m

Step-by-step explanation:

m1=9 kg m2=15 kg L=4.3 m  x+y = L M1=M2  x+y=L m1 x = m2 y  m1 x=m2 (Lx) 9 x=15 (4.3x)  24x=64.5  x=2464.5=2.6875  x=1643=2.6875=2.69 m
