3. Tension is a response force like normal force, it only happens when a mass or a force is applied to a string, rope, chain, etc. If a monkey was to hang by one arm as seen below, then we can find out what the tension in each side of the rope has to be. (a) If the monkey has a weight force of 98N, what is the vertical force that each side of the rope has to support? O is 48 degrees (b) Ok, so now if both the inside angles are 48 degrees, we can find T, since we know Ty and the angle. Calculate T in both ropes.
