O 300 mm 30° 30° A P 300 mm B The two wires are connected togetherat A. If the force P causes point A to be displaced horizontally 2 mm, determine the normal strain developed in each wire.

Problem 3: Inputs: ● F = 1800 N P = 600 N (same as previous problem) a = b = 3 m (same as previous problem) c = 8 m (same as previous problem) The frame is comprised of two members. All joints are pinned. Compute the reactions at pins A and C, as well as the forces at pin B. P с a) Ax (Indicate left/right) b) Ay (Indicate up/down) c) Cx (Indicate left/right) d) Cy (Indicate up/down) e) Bx (no need to indicate direction since this is an internal force) f) a F B b C Net force in y-direction at pin B, using the FBD for bar BC. This is not necessarily By by itself. Again, no need for direction here.

(6) Determine the reactions at A and B for the beam subjected to the uniform load distribution. Draw the N,V,M diagrams. y I 4 kN/m L--x B 500 mm- A) A 400 mm-

The bar is snugly fit between points C and A before the loading is applied at Collar B. Assume E = 200 GPa for the steel. The circular bars in the assembly are solid. The bars are solid with a diameter of 15 mm. Assume a fixed rigid support at C and A. A C В 6 kN 3 m 2 m A) Show the FBD and compatibility equation for this problem. B) Determine the support reactions at A and C. (Horizontal forces only) Left side: Fc = Right side: FA =
