Learning Goal: To develop the ability to break a frame or machine down into subsystems and to determine the forces developed at internal pin connections. Frames and machines are systems of pin-connected, multiforce members. Frames are designed to support loads, whereas machines are designed to transmit or alter the effects of loads.For a frame or machine to be in equilibrium, each member of the frame or machine system must be in equilibrium. Free-body diagrams s of the overall system, as well as individual members, groups of members, and subsystems, must be drawn.

For the free-body diagram, it is important to identify the appropriate reaction forces and couple moments that act in three dimensions. At a support, a force arises when translation of the attached member is restricted and a couple moment arises when rotation is prevented.For a rigid body to be in equilibrium when subjected to a force system, both the resultant force and the resultant couple moment acting on the body must be zero. These two conditions are expressed as The J-shaped member shown in the figure(Figure 1) is supported by a cable DE and a single journal bearing with a square shaft at A.

Learning Goal: To draw the free-body diagram of a point particle, use the equations of equilibrium to find unknown forces, and understand how frictionless pulleys affect the transfer of force in a cable. As shown, a mass is suspended from a cable that wraps around a frictionless and massless pulley. The cable connects to a linear elastic spring. For this problem, treat the pulley as a point particle at B. (Figure 1) Figure B X 1 of 1

1–2. Figure C1.2 shows a mechanism that is typical in the tank of a water closet. Note that flapper C is hollow and filled with trapped air. Carefully examine the configuration of the components in the mechanism. Then answer the following leading questions to gain insight into the operation of the mechanism. 1. As the handle A is rotated counterclockwise, what is the motion of flapper C? 2. When flapper C is raised, what effect is seen? 3. When flapper C is lifted, it tends to remain in an upward position for a period of time. What causes this tendency to keep the flapper lifted? 4. When will this tendency (to keep flapper C lifted) cease Plz connect me if you want to explan subject for me .... +962 79180149 Thx
The shaft pulley system has a universal joint at point 0. So it is supported by a slide at point A bearing and fixed support at point C. There is a mass of 12kg on the pulley and subject to the belt tensions but the mass of the shaft is negligible. a) draw the FBD of the assembly b) write the static equilibrium equations for the assembly c) explore the assembly and come up with the possible FBD for each component d) write the static equilibrium equations for the each component FBD.
