ENG MECH LAB ASSIGNMENT (1)

B4

Find the force on each member of the truss and indicate if they are under tractionor compression.   I am having difficulty in the decompositions of forces. if you can, put this in detail.I already found the reaction forces and they are in the image below. Thank you very much in advance

Please answer the problem completely. Provide a free body diagram. Final answer: • Pac = 8.84 kN (Compression) • Normal Stress = 8.84 kN (Compression)

Solve the problem shown below. Each answer is worth equal credit. Show all necessary steps of your work clearly to obtain credit. Final answer must be to 3 significant figures and contain units and be in the box. Using P1= 6.0 kips, then determine the reactions and member forces of the truss. a) List reactions at A and K? (Use positive, +, to indicate a reaction that is up, to the right, and counterclockwise.) [30 pts] RAX: RAY: Rkx: Rky: b) Determine the member forces using either the method of joints or method of sections.

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.

I need help with this review problem Engineering Statics  Take F1 = 40 kN, F2 = 20 kN, and d = 8 m (a) Draw a free body diagram of the entire truss.  (b) Find the support reaction at A (Give the x and y components) (c) Consider a cut through members CD, DI and HI.  Draw the free body diagram of the left part of cut. (d) Use the FBD of the previous question to find the tensions in members CD, DI and HI.

Please give the solution clearly, I will vitebit up for your effort if it is correct, thank you in advance

Please clearly state the formulas used and the complete solution. Thank you!

I can't quite figure this out I find all the forces but I keep getting stuck trying to figure out the internal forces like the questions ask can you help me figure this out?
