The vertical structure ABCD shown in Figure 1(a) is subjected to a system of coplanar forces and a moment. The structure is simply supported at D with a frictionless pin and is roller-supported at A. 1. (a) i. Sketch the free body diagram (FBD). Take moments about D and hence find the reaction force at support A. ii. 35 kNA 25m 05m 80 kN 60 75 KN 100 Nm 2m C. 05m 45 Fiqure 1(a)

Original problem: Set up equations needed to determine moments acting at joints as function of flexural rigidity using Force Method. Joint A - fixed support Joint B- rocker Joint C- pin (hint: pin at the end of the beam) 10 kN/m 9 m 6 m. MAn= MBA= Mac= Moment equilibrium equation at B:

Q1 -A- A man stands on the middle rung of a 250 N ladder resting on a smooth floor and against a wall as shown in Figure. The ladder is prevented from slipping by a string OD and the tension force in the string is 50 N, and the reactions at A and B are 1.3 kN and 433 N respectively. Find the mass of the man. 250 N e 30% 2m 0

Figure 1 below shows the bronze and galvani pipes are fastened to rigid supports at ends A and B and to a rigid plate C at their junction. The bronze pipe is twice as long as the galvani pipe. Two equal and symmetrically placed loads P act on the plate at C 1)Write one equilibrium equation involving reaction forces of the pipes with the help of free body diagram.[Note: Show all the forces acting on the members.]  2)Derive equilibrium equations for internal forces for section AC and BC with the help of respective free body diagrams.[Note: Show all the forces acting on the members.]

Only c part plzzzz asap...hand written plz asap.. I'll rate

k 2 13 ki Rigid bar k3 3 for the system shown in the figure, which of the following statements are correct. * u2 = P %3D !! u = u2 = U3 = U4 = 0

Solve the following problems completely, and make a detailed solution. Use ONLY AREAMETHOD in finding the V-M Diagram.  Please input the units in steps. Thankyou!

A bridge truss extends x = 206 m across a river (shown in the figure below) where 8 = 39º. The structure is free to slide horizontally to permit thermal expansion. The structural components are connected by pin joints, and the masses of the bars are small compared with the mass of a 1340 kg car at the center. Calculate the force of tension or compression in each structural component (in N).
