An automobile weighing 3900 lbs has 29-inch diameter wheels. Assuming the coefficient of rolling resistance between the tires and the road of 0.02 inch, determine the force necessary to overcome rolling friction on a level road.

3. A cylindrical buoy 600 mm in diameter and 1.8 m high weighs 205 kg. It i moored in salt water to a 12 m length of chain weighing 12 kg per m of its length. At high tide, the height of buoy protruding above water surface is 0.84. What could be the length of protrusion of the buoy if the tide dropped 2.1 m? Density of steel is 7,790 kg/m. Use density of water = 1000 kg/m³. W, = 205 kg %3D 0.6m 0 W = 205 kg 0.84 0.6m o 1.8m 2.1 m 0.96 BF, 1.8m D. BF', H' BF2 L Chain L' BF' Figure a: High Tide Figure b: Low Tide

A cylinder is rolled up an incline by a tape, as shown. What is the minimum force, T, required, if the angle of the incline is O = 30° ? The mass of the cylinder is 900g and the height of the incline is 0.6 meters. Mg sine Mg cose Mg

Please help. Written on paper not typed on computer or keyboard please. Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

Needs Complete typed solution with 100 % accuracy.

A trunk is cut and held by a tree feller as shown. If the hydraulic cylinder AC in this position is known to experience a compressive force of 283.46 kN, determine the corresponding (a) weight of the trunk, and (b) the pin reactions at B. All dimensions are in cm. Solution with incorrect FBD will not be considered. Also, all required forces should be reported in kN. k 230 A 205 B 20 75 110 HELIO All dimensions are in cm.

Figure The figure shows a schematic of an engine. F, is the force exerted by the combustion gases on the piston (shown by the rectangle at B). FÅ= 50 kN. The angle of the crank OA is 0 = 30° while the angle of the connecting rod AB is p = 15°. Neglect the weight of all members. Also neglect friction between the piston and the cylinder.
