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

Having found FcD in the analysis of joint C, there are now only two unknown forces acting on joint D. Determine the two unknown forces on joint D. 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: A column with a wide-flange section has a flange width b = 200 mm , height h = 200 mm, web thickness tw = 8 mm , and flange thickness tf = 12 mm (Figure 1). Calculate the stresses at a point 75 mm above the neutral axis if the section supports a tensile To calculate the normal and shear stresses at a point on the cross section of a column. normal force N = 2.9 kN at the centroid, shear force V = 4.6 kN, and bending moment M = 4.8 kN • m as shown (Figure 2). The state of stress at a point is a description of the normal and shear stresses at that point. The normal stresses are generally due to both internal normal force and internal bending moment. The net result can be obtained using the principle of superposition as long as the deflections remain small and the response is elastic.

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 or machine to be in equilibrium, each member of the frame or machine system must be in equilibrium. Free-body diagrams of the overall system, as well as individual members, groups of members, and subsystems, must be drawn.

Analysis and Interpretation of vertical Ground Reaction Forces. In this study, a volunteer was asked to walk on two force platforms under two different conditions. Condition 1- Normal Walk (NW), condition 2 - walking over an obstacle (ObsW). The right limb was the one to step on platform 1 in both conditions. The force platforms were used to measure the vertical ground reaction forces on the right limb. Data was collected on Vicon (Nexus) software and the attached graphs ( mean NW/ObsW, Mean (+-)1SD NW/ObsW) were created. Analyse ,Interpret the graphs and make a conclusion of the result attached.

Learning Goal: Use the two loadings below and the principle of superposition to answer the following questions. To use the method of superposition to calculate a beam deflection and slope. For beams with small deflections, the assumptions for using the method of superposition apply: the deflections and slopes are linearly related to the load, and the deflections do not significantly change the original geometry of the beam. Load The deflections and slopes for beams subjected to multiple loads can then be found using linear combinations known results for individual loads. -(--4) -5w L 384EI -5wz Lª 768EI -w L -3wz L" 24EI 128EI w L 24EI 7wz L" 384EI OR Part A - Determine the load combination A beam is subjected to the loading shown (Figure 1) where wa = 2 kN/m and w, = 2.5 kN/m.

Learning outcome Fundamental.8 evaluation Fundamental.8 deals with the equation of motion. The use of the equation of motion to solve this problem is mandatory. Solution using other approaches (conservation of energy...) will be automatically considered false. For the problem related to Fundamental.8 sketches of the system showing: the respective velocity and acceleration and the frame of reference considered . the forces acting on the system of considered, in other words, a free body diagram (FBD) are mandatory. Their absences will automatically make the problem false. A force P is applied at an angle 0 =53 to a 889-kg cart. The kinetic friction coefficient on wheels is 0. P . B 0.4 m 0.3 m Go B -0.2 m 0.3 m 0.08 m The acceleration of the cart is 1.6 m.s^². 1. What is the magnitude of the force P (answer on your hand-written work and in the cell below)? 2. What are the reaction at A and B?

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. The positive direction for the rotation is also shown in the second figure. The stresses in the rotated coordinate system are given by the following equations: στ σy + cos 20+Try sin 20 2 2 σετ συ = σy' cos 20-Try…
