Blocks A and B of mass 6 kg and 2 kg respectively are connected by a light inextensible rope hung over a light smooth pulley. Calculate the tension in the rope.
Since the rope is inextensible, block A will have the same downward acceleration as block B’s upward acceleration. Also the tension forces must be between 2g and 6g in order for block A and B to experience a net upward and downward force respectively
- Considering both blocks as a combined 8 kg mass,
- Considering block A by itself as a 6 kg mass,
- Alternatively, we can consider blocks B by itself as a 2 kg mass.
