[SOLVED] tension of sign 1. The problem statement, all variables and given/known data find force of tension in the chain and determine the force of compression in the support bar. box weighs 20.4 kg or approx. 200N ok so it doesn't give a chain length bar length nothing, so would the tension on the chain have to be equal to the weight of the box at 200N? and for the force of compression that just means the force the wall exerts on the bar? im confused about a few problems but ill start with this one.
