Presentation transcript:

Additional Forces Force applied via a cord, rope, chain, etc. is a force of…. TENSION! The force of tension is the same throughout each rope or cord.

Example 9 You are trying to drag not one but two suitcases through the airport for your European graduation adventure. Your first suitcase has a mass m 1 = 25.0 kg while your second has a mass m 2 = 20.0 kg. The two are connected together by a rope that you use to exert a horizontal force of 50.0 N. The floor is pretty slick in the airport, so virtually frictionless. Equilibrium or Non-equilibrium  F x : Equilibrium or Non-equilibrium  F y : A.Draw a FBD B.What is the acceleration of the system? C.What is the force of tension in the rope between the suitcases?

Example 10 Two blocks are connected to each other. Block A is sitting on a frictionless table and block B is hanging off the table vertically as shown. A.Find the acceleration of the blocks B.Find the tension in the rope which connects the blocks Block A 30 kg Block B 46.7 kg
