The double pulley consists of two parts that are attached to one another. It has a weight of 47 lb and a centroidal radius of gyration of ko= 0.6 ft and is turning with an angular velocity of 20 rad/s clockwise Determine the angular velocity of the pulley at the instant the 20-lb weight moves 2 ft downward Express your answer to three significant figures and include the appropriate units.

Question 6 a) The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm² and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine. c) Figure Q6c shows a pulley system with a suspended load w of 2000 N. Calculate the following: (i) (ii) (iii) (iv) The effort force (FEffort) necessary to lift and hold a load of 2000 N. The ideal mechanical advantage…

Engineering materials can be classified as being either metals or nonmetals. Medals can be subdivided into Ferris and nonferrous metals and Ferris metals can be divided into plain carbon steel, alloy steel, and cast-iron.
