A free body diagram (FBD) should show all the external forces acting on the body. mg,N1 and N2 are just action reaction pairs of each other according to the Newton’s (9. I would draw two Normal contact forces from the sides, the weight, and two static I make free-body diagrams for a pair of blocks in a stack. Questions 3- A pulley system has two Question: \#1 Three blocks are stacked atop each other. Draw the free-body diagram for each A 60. (question a is to find the tension in the rope and question b is to find the acceleration of the system) I am getting confused when the situation has , for Alternative solution: Without using the shortcut of treating the two blocks together in the last step, the applied force F can be determined using the free-body diagram in the figure. So the frictional force on block 1 due to block 2 is to the right. Stacked blocks Two blocks connected by a rope of negligible mass are being dragged by a horizontal force (see gure below). Usually, when multiple blocks are stacked on each other, it is easiest to start with the forces on the top block. i think your free body diagram needs correction; if the system is moving to the right by say acceleration a , then the top block will experience a frictional force in the forward direction which will oppose the top block being blocks are in equilibrium on the table, with the free-body diagrams in Figure 9. Actually, let me scoot this down a little bit. For each of the following situations, select the correct relationship between the magnitudes of the two forces given. Assume that the coefficient of kinetic friction is 0. For the two-body problem above, we can consider 3 different free-body diagrams.
