Consider two masses that hang from an overhead beam. The first mass of 86.4 kg is attached to the beam using an ideal rope. The second mass of 20.8 kg is attached to the first mass with an ideal rope and hangs directly under the first mass.

Question

Consider two masses that hang from an overhead beam. The first mass of 86.4 kg is attached to the beam using an ideal rope. The second mass of 20.8 kg is attached to the first mass with an ideal rope and hangs directly under the first mass.
(a) Find the tension in the lower rope. 
b) Find the tension of the upper rope

Damon · Answer

On earth I assume weight on first line = (86.4+20.8)(9.81) weight on second (lower) line = 20.8 (9.81)
