For m1: m1•a=T1
For m2: m2•a=m2•g – T2
For pulley: I•ε = M => I•a/R= (T2-T1)R => (T2-T1) = I•a/R²
a(m1+m2+ I/R²)=m2•g
a= m2•g/(m1+m2+ I/R²)
T1= m1•m2•g/(m1+m2+ I/R²)
T2 = m2•g -m2•a=...
I am geting .875 for my acceleration and its saying its wrong! Was your value this small?
For m1: m1•a=T1 (block m1=1 kg is on the surface )
For m2: m2•a=m2•g – T2 (m2=9 kg)
For pulley: I•ε = M => I•a/R= (T2-T1)R => (T2-T1) = I•a/R²
a(m1+m2+ I/R²)=m2•g
a= m2•g/(m1+m2+ I/R²) =9•9.8/{1+9+(0.3/0.25)}=7.885 m/s²
T1= m1•m2•g/(m1+m2+ I/R²)
FOr my Tension 1 I am getting 7.875 and its wrong, im so confused what im doing wrong!
T1=m1•a=1•7.885 = 7.885 N
