Q.5) A moment and four forces are applied to a two-dimensional frame as shown in figure below. Replace the given force system by a resultant force system acting at point A. Then replace the resultant force system by the simplest resultant and find x and y intercepts of its line of action. 50 lb 10 in. 80 lb 18 in. 14 in.- 75 lb B E 12 in. 100 in.-lb 90 lb -16 in. 16 in.-

5. Use the method of components to determine the resultant force acting on the system below. State the magnitude, direction, and sense of the resultant force. F₂ = 450 N 45° y F₁ = 300 N 5 4 3 F3 = 600 N

In the frame shown below, what is the value of horizontal reaction force component at C? (note: enter your numeric answer only. No need to enter units. Give your answer to two decimal places) and negative for left. Horizontal force component at C, Cx = N 2000 N B. 3 m 2 m 2 m 60°

1. Given: A structure shown below Find: (1) Determine the magnitudes and locations of the two distributed loadings. In other words, determine the magnitude and location of the loading between A and C, and those of the loading between D and B. (2) For the member DEB, (a) take the moment at B and find the reaction at E and (b) then find By by either Fy= 0, or EMp = 0. (Recall that support conditions at B and E are rollers, so there are no reactions in x-direction.) (3) For the whole structure, 3 unknown forces and moment at A (Ax, Ay and Ma) are the only unknowns. Determine those 3 unknowns at A. 900 N/m 900 N/m B A C D 2E - 3 m 3 m - 4 m - 3 m3 m-
