A large uniform chain is hanging from the ceiling, supporting a block of mass 48kg. The mass of the chain itself is 15 kg, and the length of the chain is 2.6 m.
The acceleration of gravity is 9.81 m/s^2
Find the tension in the chain at the point where the chain is supporting the block.
Answer in units of N
The chain mass is irrelevant to the problem.
Look at the block alone.
Tension T up from the chain
Weight down W = m g
no acceleration so
T = m g
T = 48 * 9.81 Newtons
