The vertical structure ABCD shown in Figure 1(a) is subjected to a (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. i. Sketch the free body diagram (FBD). ii. Take moments about D and hence find the reaction force at support A. 35 kNA A5m 05m 80 kN+ B. 60 100 kNm 75 KN 2m 05m 45

The simple truss is loaded by a system of forces as shown in the figure. The truss is supported by a pin at D and a roller at C. If P = 800 lb, then the force developed in the member (AB) is. 500 lb -3 ft DI 3 ft 3 ft FL 3 ft A Select one: O a. 800 lb - Compression Ob. 1000 lb - Compression O c. 1200 lb - Tension Od. 1020 lb - Compression

Find forces in members BC, CF, FE

Part D - A tractor shovel The tractor shovel shown (Figure 4) carries a 550 kg load that has its center of mass at H. The shovel's dimensions are: a = 52.0 mm, b = 208 mm, c = 312 mm, d = 104 mm, and e = 364 mm. Find the reaction force at E. Assume that the positive direction of the a and y axes is to the right and upward, respectively. Figure 4 of 4 Enter the Cartesian components of the reaction force at E separated by a comma.
