The tractor of a barrel train provides a tractive force of 193 lb. The 210-lb driver sits on the 850-lb engine. The tractor pulls 5 barrels; each 1.9-slug barrel holds a 45-lb kid and has a resistance force of 15 lb from the wheels. The train is driving up a hill with a 4% incline. What is the magnitude of the coupling force between the tractor and the first barrel? Two FBD = KD are required for full credit. In-Class Problem 2 A 14-kg box is on a level floor. Dr. Martin pushes on the box to the right with a 310 N force at an angle 29 above the floor. Dr. Bennett adds another item into the box so that the box will not move unless Dr. Martin applies a greater force. Determine the minimum mass of the item that Dr. Bennett added to the box to keep it from moving. The coefficients of static and kinetic friction are 0.7 and 0.5, respectively. A FBD = KD is required for full credit. The tractor of a barrel train provides a tractive force of 193 lb. The 210-lb driver sits on the 850-lb engine.
