Learning Goal: To learn to apply the method of joints to a truss in a systematic way and thereby find the loading in each member of the truss. In analyzing or designing trusses, it is necessary to determine the force in each member of the truss. One way to do this is the method of joints. The method of joints is based on the fact that if the entire truss is in equilibrium, each joint in the truss must also be in equilibrium (i.e., the free-body diagram of each joint must be balanced). Consider the truss shown in the diagram. The applied forces are P₁ = 630 lb and P₂ = 410 lb and the distance is d = 8.50 ft. Figure 1) 1 of 1 A E 30° d B D P₁ 30° d C

Express your answers in newtons to three significant figures. Enter negative value in the case of compression and positive value in the case of tension. Enter your answers separated by a comma.

Learning Goal: To describe the shape and behavior of cables that are subjected to concentrated and distributed loads. Part A Structures often use flexible cables to support members and to transmit loads between structural members. Because a cable's weight is often significantly smaller than the load it supports, a cable's weight is considered negligible and, therefore, not used in the analysis. In this tutorial, cables are assumed to be perfectly flexible and inextensible. Thus, once the load is applied the geometry of the cable remains fixed and the cable segment can be treated as a rigid body. Cables of negligible weight support the loading shown. (Figure 1) If W, = 85.0 N , W, = 510 N, YB = 1.40 m, yc = 2.80 m, yp = 0.700 m, and zc = 0.850 m, find zg.

Learning Goal: To calculate minor head losses and pressure drops for pipe fittings. Minor losses in pipe flow are the result of disruptions to the steady laminar or turblent flow in a pipe by entrances, bends, transitions, valves or other fittings. In general, calculating these losses analytically is too complex. However, all of these losses can be modeled using terms of the form h = KL where Kr, is called the loss coefficient and is determined experimentally. This coefficient relates the minor head loss to the velocity head for the flow. For expansions and contractions, the loss coefficient is calculated using nine the velocity for the smaller diameter pipe. The table below gives some representative values for various minor head losses. These are representative only, and a more complete table would account for different kinds of fittings and connections (like threaded or soldered). Fitting Well-rounded entrance ≥0.15 Flush entrance Re-entrant pipe Discharge pipe Sudden contraction (d₂…

Learning Goal: To use equilibrium to calculate the plane state of stress in a rotated coordinate system. In general, the three-dimensional state of stress at a point requires six stress components to be fully described: three normal stresses and three shear stresses (Figure 1). When the external loadings are coplanar, however, the resulting internal stresses can be treated as plane stress and described using a simpler, two-dimensional analysis with just two normal stresses and one shear stress (Figure 2). The third normal stress and two other shear stresses are assumed to be zero. The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are given in one coordinate system (Figure 3), the equivalent stresses in a rotated coordinate system (Figure 4) can be calculated using the equations of static equilibrium. Both sets of stresses describe the same state of stress. The stresses σx′and τx′y′ can be found by considering the free-body…

Learning Goal: To be able to solve three-dimensional equilibrium problems using the equations of equilibrium. Part A As with two-dimensional problems, a free-body diagram is the first step in solving three-dimensional equilibrium problems. 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 use transformation equations to calculate the plane state of stress in a rotated coordinate system. The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are given in one coordinate system (Figure 1), the equivalent stresses in a rotated coordinate system (Figure 2) can be calculated using a set of transformation equations. Both sets of stresses describe the same state of stress. In order to use the transformation equations, a sign convention must be chosen for the normal stresses, shear stresses, and the rotation angle. For the equations below, a positive normal stress acts outward on a face. A positive Try acts in the positive y-direction on the face whose outward normal is in the positive x-direction.
