Strategic Analysis: - Draw a free body diagram for each object and create net force and torque equations for each. - Solve the equations for the acceleration.

Figure 5.32 (a) The free-body diagram for isolated object A. (b) The free-body diagram for isolated object B. Comparing the two drawings, we see that friction acts in the opposite direction in the two figures. Because object A experiences a force that tends to pull it to the right, friction must act to the left. Because object B experiences a component of its weight that pulls it to the left ...

Theory When two masses are suspended by a string over a pulley (Figure 1) each feels a downward force due to its weight (W=mg) and an upward force due to the tension (T) in the string (Figure 2). If these two forces are equal, then the net

Pulley system free body diagram. • Establish inertial coordinate system • Identify and isolate discrete system elements (springs, dampers, masses) • Determine the minimum number of variables needed to uniquely define the configuration of system (subtract constraints from number of equations) • Free body diagram for each element Find: Draw the free-body and kinetic diagrams of the crate. Plan: 1) Define an inertial coordinate system. 2) Draw the crate's free-body diagram, showing all external forces applied to the crate in the proper directions. 3) Draw the crate's kinetic diagram, showing the inertial force vector ma in the proper direction. The free-body diagram for the forces acting on the moving pulley is shown in Figure 8.41(d). Newton’s second Law applied to the pulley is ˆ. j: 2T −. T = m a. B A P y P, = 0 . (8.6.55) Because the pulley is assumed to be massless, we can use this last equation to determine the condition that the tension in the two strings must satisfy, 2. T. B = T. A (8.6.56) A free body diagram shows all of the forces acting on an object, even if their effects are balanced out by another force. We will use free body diagrams to consider different situations involving the lamp that you find at your lab station (Figure 3.1 ). One force that always acts on the lamp is gravity.

FREE-BODY DIAGRAMS (Section 5.2) 2. Show all the external forces and couple moments. These typically include: a) applied loads, b) support reactions, and, c) the weight of the body. Idealized model Free-body diagram (FBD) 1. Draw an outlined shape. Imagine the body to be isolated or cut "free" from its constraints and draw its outlined shape. Department of Mechanical Engineering Force equilibrium (mechanical eql.) (Mechanical) equilibrium requires that the concurrent forces that act on the body satisfy The particle in a equilibrium system must satisfy Since both must be satisfied, the material point then must have zero acceleration, a = 0 R =∑F =0 R =∑F =m.a The free body diagram helps you understand and solve static and dynamic problem involving forces. It is a diagram including all forces acting on a given object without the other object in the system. You need to first understand all the forces acting on the object and then represent these force by arrows in the direction of the force to be drawn.

The free-body diagrams for each individual mass are shown below. Each object is experiencing a downward force of gravity - calculated as m 1 •g and m 2 •g respectively. Each object is also experiencing an upward tension force that pulls the two objects towards each other.

Using free body diagram as shown above, Block1: There is a tension force and frictional force in opposite directions. Fnet = T - friction => T = μ k *m 1 *g + m 1 *a. Block 2: There is an applied force towards the right. The tension and frictional force are acting in the same direction. Fnet = F - T - friction => T = F - μ k *m 2 *g ...
