Suppose in a scenario a weight is hanging on a string from a rod. There is a second string at the end of the weight: ------rod--------- ______|___thread1 ------weight----- -------|---thread 2 Now suppose a person's hand pulls on the bottom string. How would the force diagram be drawn? There is a force of tension above the weight, but what about the others forces (like the 1 below the weight)? What is going on? Please help with the other force(s). Thanks.
