Question

If M1 be the mass of 1st body, M2 be the mass of 2nd body and r be the radius find the dimensions of force?​

Answer 1

Answer:

Force balance equations for two weights can be written as:

T1=m1g−m1a---------(i)

and T2=m2a+m2g----------(ii)

(ii)-(i), we get:

T1−T2=(m1−m2)g−(m1+m2)a------------(iii)

As torque, τ=Iα, we have:

(T1−T2)R=(21MR2).Ra

or, T1−T2=2Ma

Substituting this in equation (iii), we get:

2Ma=(m1−m2)g−(m1+m2)a

or, a=m1+m2+(m/2)(
