Question
two masses m1 and m2 are lying on a horizontal plane without friction and are connected by a string. the third mass m3 is hanging vertically over a pulley, connected by a string to masses m1 and m2. what are the tension forces between different masses? what are the acceleration of the system? two masses m1 and m2 are lying on a horizontal plane without friction and are connected by a string. the third mass m3 is hanging vertically over a pulley, connected by a string to masses m1 and m2. what are the tension forces between different masses? what are the acceleration of the system? two masses m1 and m2 are lying on a horizontal plane without friction and are connected by a string. the third mass m3 is hanging vertically over a pulley, connected by a string to masses m1 and m2. what are the tension forces between different masses? what are the acceleration of the system?Explanation / Answer
For m3
m3*g - T32 = m3*a
T32 = m3*g - m3*a (1)
for m1
T12 = m1*a (2)
for m2
T32 - T12 = m2*a
m3*g - m3*a - m1*a = m2*a (3)
from 3
a = m3*g/(m1+m2+m3)
T32 = m3*g - m3*m3*g/(m1+m2+m3)
T32 = m3*g*(m1+m2)/(m1+m2+m3) <<<<-------answer
T12 = m1*a = m1*m3*g/(m1+m2+m3) <<<<-------answer
acceleration a = m3*g/(m1+m2+m3) <<<------answer
