8. Determine the location of the center of mass of the cylinder shown in the figure if its density varies directly with the distance from its base, i.e., p = 200z kg/m². 0.5 m 1 m (0,0, 2)- dz

The pipe assembly in is secured on the wall by the two brackets. MOA = 60° lb. ft 4 ft 4 ft 3 ft 30⁰ 3 ft Part A If the flowerpot has a weight of 50 lb, determine the magnitude of the moment produced by the weight about the OA axis. Express your answer in pound-feet to three significant figures. ANSWER: B y

The cylinder having a diameter 2.5 ft weighs 57 lb and is 6 ft long. Determine the reaction (lb.) at A neglecting friction. Determine the reaction at B (lb.) neglecting friction. Weight density of water is 62.4 lb/ft3 Sp.gr Gs = 1.6

The lift sling is used to hoist a container having a mass of 500 kg. The center of gravity of the container is located at G. Part A Draw free body diagram of the ring A. Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded. No elements selected -1.5 m 1.5 m *G

2-50. The uniform rectangular relief gate AB has a weight of 8000 lb and a width of 4 ft. Determine the minimum depth h of water within the container needed to open it. The gate is pinned at B and rests on a rubber seal at A. h 6 ft 30

Determine the magnitude of the reactions at A and C (resultant). Neglect the weight of the bar.

A truck is driving over a scale at a weight station. When the front wheels drive over the scale, the scale reads 5800 N.  When the rear wheels drive over the scale, it reads 6500 N.  The distance between the front and rear wheels is 3.20 m Determine the distance between the front wheels and the truck's center of gravity.

Determine the force on hinge C and block D if the gate holding the water is 4 meters wide into the page

The concrete gravity dam is held in place by its own weight. If the density of concrete is 2.5 Mg/m3, and water has a density of 1.0 Mg/m³, determine the magnitude of the total resultant force the water exerts on the dam. The width of the dam is 10 m, and d=3 m. F m- 6 m -d – 1–| 1861 kN 1789 kN 1776 kN 1941 kN 1960 kN
