A force P is applied at B where P=12i-17j kN.the reaction force at A acts along the boom because it is a two force member. Calculat the magnitude of the reaction force at A in kN
- Two bars are subjected to F=20 kN force as shown in Figure and atemperature rise of 100 0C. DetermineReaction forces at the walls A and B. The change in length of the bronze barInclude the Free body diagram ,and don't provide previously solved answers.Determine the force in each member of the truss, and state if the member is in tension or compression. Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression.

- PROBLEM: Determine the forces in each member using any methoddiscussed in your theory of structures/mechanics. Using Software is notallowed. Show complete solution and tabulate your answers indicatingwhether it is compression or tension. Use Pn = 205 kN, Po = Zero. a) From the Problem and the image , Design one tension member, use either a double angle of a wt section. Check its adequacy using 1 line of bolts (three bolts in a line spaced at 75mm on centers) Assume a bolt diameter from 16-22mm. Use A 36 for all steel. Neglect block shear.Find the support reacions and joint force of the construction shown on the figure, if; P=12 kN q=9 kN/m M=12 kN and L=2 mConsider the force P applied at point A on the plate of the figure shown (image 1). Assuming that the weight of the plate is negligible, and that the horizontal force F, as well as the reactions Dy and Dx in the joint D balance the plate shown in the figure, choose the alternatives that are true. Note: the x-axis is horizontal and the y-axis is vertical and both have their origin at point D. Data: P = 332N If the plate had a weight of 332N (applied vertically downwards in the center of the plate), the reaction Dy on the plate should be vertical downwards so that the plate still remained in balance in that position. True or false?
