Suppose the smaller pulley of the previous problem has its radius 5.0 cm and moment of inertia 0.10 kg-m2. Find the tension in the part of the string joining the pulleys.
The tension on the string is given as ![]()
Given
The moment of the inertia of the wheel is given as 0.20
and a radius of 10 cm to support/hang a block of 2 kg mass.
Formula Used
The formula used to find the torque applied on the pulley due to the masses are described below as the product of moment of Inertia and angular acceleration:
![]()
where
is the torque of the pulley,
is the angular acceleration and I is the moment of Inertia of the pulley
