1. The force in the strut AB  2. the horizontal component at the pin C  3. the vertical component at the pin C

A statically determinate truss is one of the early problems addressed in sophomore statics classes. A typical problem is shown in figure below: 2 Fapplied √30° F₁ F3 F2 02 3 L. Hinge Roller The applied force has a magnitude of 1000 N at an angle of 30° from the horizontal, as shown in the figure. The inner angles ₁ and 2 are 45° and 65° respectively. Determine the values of the forces in each member of the truss, and the reactive forces experienced at the hinge and the roller (nodes 2 and 3). Set up the problem using a simultaneous equation system. Use the method of the inverse matrix taught in the lectures. Follow the steps a) to e) as indicated below (assume "S" as the matrix representing the previous system. a) Calculate the matrix of minors of S. b) Calculate the matrix of cofactors of S (name it H) c) Calculate the determinant of S. d) Calculate the Adjoint of matrix of S using adj S = HT e) Calculate the inverse of matrix S using S₁ = adj S/|S|

Help!!! Answer this correctly!! Please

Find the true magnitude and direction of the forces in all members of the truss AB and AC at static equilibrium.

QUESTION 1 Determine the reaction moment at x = 0 in kN-m. QUESTION 2 Determine the vertical reaction force at x = 0 in kN. QUESTION 3 (1-3) Determine the horizontal reaction force at x = 0 in kN. The distributed load, f(x), is equal to 100 kN/m. /// f(x) 3 m

For the next Trusses, compute the axial forces in the selected sections. Compare the result with the method of joints. (Check the image for the trusses)

4. Solve for all the force values of each member in the given system. 3 12 W = 200 # 3

need part C and D only

Answer the following question: 3. Find the horizontal and vertical components of the forces at all joints. The reaction at point B is horizontal.

1. This arm is attached to a wall on the left. The right end is free hanging. Each section is 1.9m wide and 3.6m high. If the force at the end of the arm is F = 170.0N, what is the force in member 2? Use a positive number if it is in tension and a negative number if it is in compression.   2. This arm is attached to a wall on the left. The right end is free hanging. Each section is 1.2m wide and 3.0m high. If the force at the end of the arm is F = 150.0N, what is the force in member 9?  Use a positive number if it is in tension and a negative number if it is in compression.
