Question 5 An important problem in structural engineering is that of finding the forces in a staticaly determinate truss (see tgurel 1000N 90° This type of structure cen be described as a system of the of coupled linear algebraic equations derived from force balances. The sum node because the system is at rest. Therefore, for ode 1 For node 2 For node 3 where Fis is the external horlzontal force applied to node /(where a positive torce is ve tical force applied to node (where a positive force is upward Thus nti, problem the OO ON corresponds to F-1000 For this cese, all other Fys and Pass are zero own ward force on node 1 Express the given set of linear algebraic equations in matrix form (Round the final answers to six decimal places) Using Matlab, find the values of the unknowns.

    Matlab question: Resistive networks are well-represented by linear equations. Consider the DC circuit shown below: Figure 1 This problem can be converted into a system of simultaneous linear equations by applying Kirchhoff's law and Ohm's law. In circuit design, i represents current (measured in amperes, A), V represents voltage (in volts, V), and R represents resistance (in ohms, ohm). Kirchhoff's law states that the sum of the currents entering a node is equal to the sum of the currents leaving...

    solve a-c Problem 1 (Scorelator) Consider the truss bridge diagrammed below. The bridge is composed of trusses (steel beams) that are connected at joints or nodes. Each truss exerts a force, F, on the nodes that t touches. When the bridge is at rest, these forces balance. A positive force means that the beam is in tension: it is being pulled apart by the nodes. A negative force means that the beam is being pushed inwards and is in compression...

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...
